Struct wasmer::Cranelift

pub struct Cranelift { /* fields omitted */ }

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

This structure exposes a builder-like interface and is primarily consumed by wasmer_engine::Engine::new.

Implementations

impl Cranelift

pub fn new() -> Cranelift

Creates a new configuration object with the default configuration specified.

pub fn canonicalize_nans(&mut self, enable: bool) -> &mut Cranelift

Enable NaN canonicalization.

NaN canonicalization is useful when trying to run WebAssembly deterministically across different architectures.

pub fn enable_simd(&mut self, enable: bool) -> &mut Cranelift

Enable SIMD support.

pub fn opt_level(&mut self, opt_level: CraneliftOptLevel) -> &mut Cranelift

The optimization levels when optimizing the IR.

pub fn isa(&self, target: &Target) -> Box<dyn TargetIsa + 'static, Global>

Generates the ISA for the provided target

pub fn flags(&self) -> Flags

Generates the flags for the compiler

Trait Implementations

impl Clone for Cranelift

pub fn clone(&self) -> Cranelift

Returns a copy of the value.

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

impl CompilerConfig for Cranelift

pub fn enable_pic(&mut self)

Enable Position Independent Code (PIC).

pub fn enable_verifier(&mut self)

Enable compiler IR verification.

pub fn compiler(
    self: Box<Cranelift, Global>
) -> Box<dyn Compiler + 'static, Global>

Transform it into the compiler

pub fn push_middleware(
    &mut self,
    middleware: Arc<dyn ModuleMiddleware + 'static>
)

Pushes a middleware onto the back of the middleware chain.

pub fn default_features_for_target(&self, _target: &Target) -> Features
