Struct wasmtime_environ::ModuleEnvironment

pub struct ModuleEnvironment<'a, 'data> { /* private fields */ }

Object containing the standalone environment information.

Implementations

impl<'a, 'data> ModuleEnvironment<'a, 'data>

pub fn new( tunables: &'a Tunables, validator: &'a mut Validator, types: &'a mut ModuleTypesBuilder, ) -> Self

Allocates the environment data structures.

pub fn translate( self, parser: Parser, data: &'data [u8], ) -> Result<ModuleTranslation<'data>>

Translate a wasm module using this environment.

This function will translate the data provided with parser, validating everything along the way with this environment’s validator.

The result of translation, ModuleTranslation, contains everything necessary to compile functions afterwards as well as learn type information about the module at runtime.
