Struct wasmtime_api::Config

pub struct Config { /* fields omitted */ }

Global configuration options used to create an Engine and customize its behavior.

This structure exposed a builder-like interface and is primarily consumed by Engine::new()

Implementations

impl Config

pub fn new() -> Config

Creates a new configuration object with the default configuration specified.

pub fn debug_info(&mut self, enable: bool) -> &mut Self

Configures whether DWARF debug information will be emitted during compilation.

By default this option is false.

pub fn flags(&mut self, flags: Flags) -> &mut Self

Configures various flags for compilation such as optimization level and such.

For more information on defaults and configuration options, see the documentation for Flags

pub fn features(&mut self, features: Features) -> &mut Self

Indicates which WebAssembly features are enabled for this compilation session.

By default only stable features are enabled by default (and none are fully stabilized yet at this time). If you're loading wasm modules which may use non-MVP features you'll want to be sure to call this method and enable the appropriate feature in the Features structure.

pub fn strategy(&mut self, strategy: CompilationStrategy) -> &mut Self

Configures the compilation strategy provided, indicating which backend will be used for compiling WebAssembly to native code.

Currently the primary strategies are with cranelift (an optimizing compiler) or lightbeam (a fast single-pass JIT which produces code quickly).

Trait Implementations

fn clone(&self) -> Config

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
