Enum Strategy 

#[non_exhaustive]
pub enum Strategy {
    Auto,
    Cranelift,
    Winch,
}

Possible Compilation strategies for a wasm module.

This is used as an argument to the Config::strategy method.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

An indicator that the compilation strategy should be automatically selected.

This is generally what you want for most projects and indicates that the wasmtime crate itself should make the decision about what the best code generator for a wasm module is.

Currently this always defaults to Cranelift, but the default value may change over time.

Cranelift

Currently the default backend, Cranelift aims to be a reasonably fast code generator which generates high quality machine code.

Winch

A low-latency baseline compiler for WebAssembly. For more details regarding ISA support and Wasm proposals support see https://docs.wasmtime.dev/stability-tiers.html#current-tier-status

Trait Implementations

impl Clone for Strategy

fn clone(&self) -> Strategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Strategy

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

Formats the value using the given formatter.

impl PartialEq for Strategy

fn eq(&self, other: &Strategy) -> 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.

impl Copy for Strategy

impl Eq for Strategy

impl StructuralPartialEq for Strategy
