Struct wasmer_compiler::ModuleEnvironment

source ·
pub struct ModuleEnvironment<'data> {
    pub module: ModuleInfo,
    pub function_body_inputs: PrimaryMap<LocalFunctionIndex, FunctionBodyData<'data>>,
    pub data_initializers: Vec<DataInitializer<'data>>,
    pub module_translation_state: Option<ModuleTranslationState>,
}
Expand description

The result of translating via ModuleEnvironment. Function bodies are not yet translated, and data initializers have not yet been copied out of the original buffer. The function bodies will be translated by a specific compiler backend.

Fields§

§module: ModuleInfo

ModuleInfo information.

§function_body_inputs: PrimaryMap<LocalFunctionIndex, FunctionBodyData<'data>>

References to the function bodies.

§data_initializers: Vec<DataInitializer<'data>>

References to the data initializers.

§module_translation_state: Option<ModuleTranslationState>

The decoded Wasm types for the module.

Implementations§

source§

impl<'data> ModuleEnvironment<'data>

source

pub fn new() -> Self

Allocates the environment data structures.

source

pub fn translate(self, data: &'data [u8]) -> WasmResult<Self>

Translate a wasm module using this environment. This consumes the ModuleEnvironment and produces a ModuleInfoTranslation.
