Struct wasmer_compiler::ModuleTranslationState

pub struct ModuleTranslationState {
    pub(crate) wasm_types: PrimaryMap<SignatureIndex, (Box<[ValType]>, Box<[ValType]>)>,
}

Contains information decoded from the Wasm module that must be referenced during each Wasm function’s translation.

This is only for data that is maintained by wasmer-compiler itself, as opposed to being maintained by the embedder. Data that is maintained by the embedder is represented with ModuleEnvironment.

Fields

wasm_types: PrimaryMap<SignatureIndex, (Box<[ValType]>, Box<[ValType]>)>

A map containing a Wasm module’s original, raw signatures.

This is used for translating multi-value Wasm blocks inside functions, which are encoded to refer to their type signature via index.

Implementations

impl ModuleTranslationState

pub fn new() -> Self

Creates a new empty ModuleTranslationState.

pub fn blocktype_params_results<'a>( &'a self, ty_or_ft: &'a BlockType, ) -> WasmResult<(&'a [ValType], SingleOrMultiValue<'a>)>

Get the parameter and result types for the given Wasm blocktype.

Trait Implementations

impl Debug for ModuleTranslationState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
