Enum Compiler

pub enum Compiler {
    CraneliftNative,
    Winch,
    CraneliftPulley,
}

Different compilers that can be tested in Wasmtime.

Variants

CraneliftNative

Cranelift backend.

This tests the Cranelift code generator for native platforms. This notably excludes Pulley since that’s listed separately below even though Pulley is a backend of Cranelift. This is only used for native code generation such as x86_64.

Winch

Winch backend.

This tests the Winch backend for native platforms. Currently Winch primarily supports x86_64.

CraneliftPulley

Pulley interpreter.

This tests the Cranelift pulley backend plus the pulley execution environment of the output bytecode. Note that this is separate from Cranelift above to be able to test both on platforms where Cranelift has native codegen support.

Implementations

impl Compiler

pub fn should_fail(&self, config: &TestConfig) -> bool

Returns whether this compiler is known to fail for the provided TestConfig.

This function will determine if the configuration of the test provided is known to guarantee fail. This effectively tracks the proposal support for each compiler backend/runtime and tests whether config enables or disables features that aren’t supported.

Note that this is closely aligned with Config::compiler_panicking_wasm_features.

pub fn supports_host(&self) -> bool

Returns whether this compiler configuration supports the current host architecture.

Trait Implementations

impl Clone for Compiler

fn clone(&self) -> Compiler

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Compiler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Compiler

fn eq(&self, other: &Compiler) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
