# Contributor Covenant Code of Conduct
2+
3+
## Our Pledge
4+
5+
We as members, contributors, and leaders pledge to make participation in our
6+
community a harassment-free experience for everyone, regardless of age, body
7+
size, visible or invisible disability, ethnicity, sex characteristics, gender
8+
identity and expression, level of experience, education, socio-economic status,
9+
nationality, personal appearance, race, caste, color, religion, or sexual
10+
identity and orientation.
11+
12+
We pledge to act and interact in ways that contribute to an open, welcoming,
13+
diverse, inclusive, and healthy community.
14+
15+
## Our Standards
16+
17+
Examples of behavior that contributes to a positive environment for our
18+
community include:
19+
20+
* Demonstrating empathy and kindness toward other people
21+
* Being respectful of differing opinions, viewpoints, and experiences
22+
* Giving and gracefully accepting constructive feedback
23+
* Accepting responsibility and apologizing to those affected by our mistakes,
24+
and learning from the experience
25+
* Focusing on what is best not just for us as individuals, but for the overall
26+
community
27+
28+
Examples of unacceptable behavior include:
29+
30+
* The use of sexualized language or imagery, and sexual attention or advances of
31+
any kind
32+
* Trolling, insulting or derogatory comments, and personal or political attacks
33+
* Public or private harassment
34+
* Publishing others' private information, such as a physical or email address,
35+
without their explicit permission
36+
* Other conduct which could reasonably be considered inappropriate in a
37+
professional setting
38+
39+
## Enforcement Responsibilities
40+
41+
Community leaders are responsible for clarifying and enforcing our standards of
42+
acceptable behavior and will take appropriate and fair corrective action in
43+
response to any behavior that they deem inappropriate, threatening, offensive,
44+
or harmful.
45+
46+
Community leaders have the right and responsibility to remove, edit, or reject
47+
comments, commits, code, wiki edits, issues, and other contributions that are
48+
not aligned to this Code of Conduct, and will communicate reasons for moderation
49+
decisions when appropriate.
50+
51+
## Scope
52+
53+
This Code of Conduct applies within all community spaces, and also applies when
54+
an individual is officially representing the community in public spaces.
55+
Examples of representing our community include using an official e-mail address,
56+
posting via an official social media account, or acting as an appointed
57+
representative at an online or offline event.
58+
59+
## Enforcement
60+
61+
Instances of abusive, harassing, or otherwise unacceptable behavior may be
62+
reported to the community leaders responsible for enforcement at
63+
opensourcereports@structure.io.
64+
All complaints will be reviewed and investigated promptly and fairly.
65+
66+
All community leaders are obligated to respect the privacy and security of the
67+
reporter of any incident.
68+
69+
## Enforcement Guidelines
70+
71+
Community leaders will follow these Community Impact Guidelines in determining
72+
the consequences for any action they deem in violation of this Code of Conduct:
73+
74+
### 1. Correction
75+
76+
**Community Impact**: Use of inappropriate language or other behavior deemed
77+
unprofessional or unwelcome in the community.
78+
79+
**Consequence**: A private, written warning from community leaders, providing
80+
clarity around the nature of the violation and an explanation of why the
81+
behavior was inappropriate. A public apology may be requested.
82+
83+
### 2. Warning
84+
85+
**Community Impact**: A violation through a single incident or series of
86+
actions.
87+
88+
**Consequence**: A warning with consequences for continued behavior. No
89+
interaction with the people involved, including unsolicited interaction with
90+
those enforcing the Code of Conduct, for a specified period of time. This
91+
includes avoiding interactions in community spaces as well as external channels
92+
like social media. Violating these terms may lead to a temporary or permanent
93+
ban.
94+
95+
### 3. Temporary Ban
96+
97+
**Community Impact**: A serious violation of community standards, including
98+
sustained inappropriate behavior.
99+
100+
**Consequence**: A temporary ban from any sort of interaction or public
101+
communication with the community for a specified period of time. No public or
102+
private interaction with the people involved, including unsolicited interaction
103+
with those enforcing the Code of Conduct, is allowed during this period.
104+
Violating these terms may lead to a permanent ban.
105+
106+
### 4. Permanent Ban
107+
108+
**Community Impact**: Demonstrating a pattern of violation of community
109+
standards, including sustained inappropriate behavior, harassment of an
110+
individual, or aggression toward or disparagement of classes of individuals.
111+
112+
**Consequence**: A permanent ban from any sort of public interaction within the
113+
community.
114+
115+

# StructureKit
2+
3+
A collection of helper tools for [Structure SDK](https://structure.io/developers)
4+
5+
## Installation
6+
You can consume it as a Swift Package:
7+
[Adding package dependencies to your app](https://developer.apple.com/documentation/xcode/adding-package-dependencies-to-your-app)
8+
9+
## Usage
10+
Import into your Swift source code:
11+
```swift
12+
import StructurKit
13+
```
14+
15+
### Integration with Structure SDK
16+
StructureKit based on Structure SDK - compatible interfaces.
17+
18+
Current version is compatible with Structure SDK `2.*`
19+
20+
To seamlessly use Structure SDK types together with StructureKit, add the following code in your project:
21+
22+
```swift
23+
import StructureKit
24+
25+
extension STMesh : STKMesh {
26+
}
27+
28+
extension STColorFrame : STKColorFrame {
29+
}
30+
31+
extension STIntrinsics : STKIntrinsics {
32+
}
33+
34+
extension STDepthFrame : STKDepthFrame {
35+
public func intrinsics() -> STKIntrinsics {
36+
let i : STIntrinsics = self.intrinsics()
37+
return i;
38+
}
39+
}
40+
```
