Struct cranelift_codegen::ir::entities::Inst

pub struct Inst(_);

An opaque reference to an instruction in a Function.

Most usage of Inst is internal. Instructions are returned by InstBuilder instructions that do not return a Value, such as control flow and trap instructions.

If you look around the API, you can find many inventive uses for Inst, such as annotating specific instructions with a comment or performing reflection at compile time on the type of instruction.
