Struct cranelift_frontend::FunctionBuilderContext

pub struct FunctionBuilderContext { /* fields omitted */ }

Structure used for translating a series of functions into Cranelift IR.

In order to reduce memory reallocations when compiling multiple functions, FunctionBuilderContext holds various data structures which are cleared between functions, rather than dropped, preserving the underlying allocations.

The Variable parameter can be any index-like type that can be made to implement EntityRef. For frontends that don't have an obvious type to use here, variable::Variable can be used.

Methods

impl FunctionBuilderContext

pub fn new() -> Self

Creates a FunctionBuilderContext structure. The structure is automatically cleared after each FunctionBuilder completes translating a function.
