Struct wasmer_compiler_cranelift::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() -> Self

Creates a new configuration object with the default configuration specified.

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

Enable NaN canonicalization.

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

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

The optimization levels when optimizing the IR.

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

Generates the ISA for the provided target

pub fn flags(&self) -> Flags

Generates the flags for the compiler

Trait Implementations

impl Clone for Cranelift

fn clone(&self) -> Cranelift

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CompilerConfig for Cranelift

fn compiler(self: Box<Self>) -> Box<dyn Compiler>

Transform it into the compiler

fn push_middleware(&mut self, middleware: Arc<dyn ModuleMiddleware>)

fn enable_nan_canonicalization(&mut self)

👎 Deprecated:

Please use the canonicalize_nans instead

Enable NaN canonicalization.

fn canonicalize_nans(&mut self, enable: bool)

Enable NaN canonicalization.

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

impl Default for Cranelift

fn default() -> Self

Returns the “default value” for a type.

impl MemoryUsage for Cranelift

fn size_of_val(&self, visited: &mut dyn MemoryUsageTracker) -> usize

Returns the size of the referenced value in bytes.
