Struct ModuleEnvironment

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

Object containing the standalone environment information.

Implementations§

source§

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

source

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

Allocates the environment data structures.

source

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.
