pub struct FuncEnv<'a, P> {
    pub vmoffsets: VMOffsets<P>,
    pub translation: &'a ModuleTranslation<'a>,
}

The function environment.

Contains all information about the module and runtime that is accessible to to a particular function during code generation.

Fields

vmoffsets: VMOffsets<P>

Offsets to the fields within the VMContext ptr.

translation: &'a ModuleTranslation<'a>

Metadata about the translation process of a WebAssembly module.

Implementations

impl<'a, P: PtrSize> FuncEnv<'a, P>

pub fn new(ptr: P, translation: &'a ModuleTranslation<'_>) -> Self

Create a new function environment.

pub fn callee_from_index(&self, idx: FuncIndex) -> Callee

Resolves a function [Callee] from an index.

pub fn resolve_block_type(&self, blockty: BlockType) -> SmallVec<[WasmType; 1]>

Resolves the type of the block in terms of [wasmtime_environ::WasmType].

pub fn resolve_global_type_and_offset( &self, index: GlobalIndex ) -> (WasmType, u32)
