Struct rspirv::sr::Context

pub struct Context { /* fields omitted */ }

The context class for SPIR-V structured representation.

This class holds all allocations for types, constants, decorations, instructions, etc. in structured representation. Thus, those objects are created using methods of this class. Tokens are returned for the object to be created, which can then be used to access the real object using the context again. Tokens are indeed indices into the vectors of objects inside the context. The context serves as the memory arena.
