Load()

bool Spices::ShaderLoader::Load ( const std::string & fileName, ShaderStage stage, Shader * outShader )

static

Public called API, it is entrance.

Parameters

[in]	fileName	Shader name.
[in]	stage	ShaderStage.
[in,out]	outShader	Shader pointer, only pass this to it. Feel free for using row pointer here, it's very safe, for this API only called during Shader.

Returns

Returns true if load data successfully.

Read file as bytes.

Compile to spv.

Create shader module.
