Represents the local keyword space of a Shader or ComputeShader.
Shader keywords determine which shader variants Unity uses. For information on working with local shader keywords and global shader keywords and how they interact, see Using shader keywords with C# scripts.
When you declare a shader keyword in the source file for a Shader or ComputeShader, Unity represents the keyword with a LocalKeyword and stores it in a LocalKeywordSpace.
For a Shader, access the LocalKeywordSpace with Shader.keywordSpace. It contains:
All keywords declared in the source file. For more information, see Declaring shader keywords.
All keywords declared in dependencies of that source file. This comprises all Shaders that are included via the Fallback command, and all keywords declared in all Passes that are included via the UsePass command.
All keywords that Unity adds automatically. For more information, see Unity's predefined shader keywords.
For a ComputeShader, access the LocalKeywordSpace with ComputeShader.keywordSpace. It contains all keywords declared in the source file. For more information, see Declaring shader keywords.
