unity-yaml-rust

unity-yaml-rust is a pure Rust YAML parser for Unity.

Add Unity YAML spec and mutable access Base on yaml-rust

Quick Start

Add the following to the Cargo.toml of your project:

toml [dependencies] unity-yaml-rust = "0.1"

Use yaml::YamlLoader to load the YAML documents and access it as Vec/HashMap:

```rust use unityyamlrust::{yaml::YamlLoader, emmitter::YamlEmitter};

fn main() { let s = r#" %YAML 1.1 %TAG !u! tag:unity3d.com,2011: --- !u!687078895 &4343727234628468602 SpriteAtlas: mObjectHideFlags: 0 mCorrespondingSourceObject: {fileID: 0} mPrefabInstance: {fileID: 0} mPrefabAsset: {fileID: 0} mName: atlaslaunch mEditorData: serializedVersion: 2 textureSettings: serializedVersion: 2 anisoLevel: 1 compressionQuality: 50 maxTextureSize: 2048 textureCompression: 0 filterMode: 1 generateMipMaps: 0 readable: 0 crunchedCompression: 0 sRGB: 1 platformSettings: [] packingSettings: serializedVersion: 2 padding: 4 blockOffset: 1 allowAlphaSplitting: 0 enableRotation: 0 enableTightPacking: 0 variantMultiplier: 1 packables: - {fileID: 102900000, guid: c5a32d8209c314631bad292a32582dfc, type: 3} bindAsDefault: 1 mMasterAtlas: {fileID: 0} mPackedSprites: - {fileID: 21300000, guid: 3083aff0bd42a4268a9cfe6e564ab247, type: 3} - {fileID: 21300000, guid: 054656e6c52c2425eb7c5ec764d03587, type: 3} - {fileID: 21300000, guid: 55aba929877c26747acf9ad10ee7989c, type: 3} mPackedSpriteNamesToIndex: - loginiclogo - launchiconservice - loginiclogobak1 mTag: atlaslaunch mIsVariant: 0 "#; let mut docs = YamlLoader::loadfromstr(s).unwrap();
