Struct wasmer_compiler::Features

pub struct Features {
    pub threads: bool,
    pub reference_types: bool,
    pub simd: bool,
    pub bulk_memory: bool,
    pub multi_value: bool,
}

Controls which experimental features will be enabled. Features usually have a corresponding WebAssembly proposal.

Fields

threads: bool

Threads proposal should be enabled

reference_types: bool

Reference Types proposal should be enabled

simd: bool

SIMD proposal should be enabled

bulk_memory: bool

Bulk Memory proposal should be enabled

multi_value: bool

Multi Value proposal should be enabled

Implementations

impl Features

pub fn new() -> Features

Create a new feature

pub fn threads(&mut self, enable: bool) -> &mut Features

Configures whether the WebAssembly threads proposal will be enabled.

The WebAssembly threads proposal is not currently fully standardized and is undergoing development. Support for this feature can be enabled through this method for appropriate WebAssembly modules.

This feature gates items such as shared memories and atomic instructions.

This is false by default.

pub fn reference_types(&mut self, enable: bool) -> &mut Features

Configures whether the WebAssembly reference types proposal will be enabled.

The WebAssembly reference types proposal is not currently fully standardized and is undergoing development. Support for this feature can be enabled through this method for appropriate WebAssembly modules.

This feature gates items such as the externref type and multiple tables being in a module. Note that enabling the reference types feature will also enable the bulk memory feature.

This is false by default.

pub fn simd(&mut self, enable: bool) -> &mut Features

Configures whether the WebAssembly SIMD proposal will be enabled.

The WebAssembly SIMD proposal is not currently fully standardized and is undergoing development. Support for this feature can be enabled through this method for appropriate WebAssembly modules.

This feature gates items such as the v128 type and all of its operators being in a module.

This is false by default.

pub fn bulk_memory(&mut self, enable: bool) -> &mut Features

Configures whether the WebAssembly bulk memory operations proposal will be enabled.

The WebAssembly bulk memory operations proposal is not currently fully standardized and is undergoing development. Support for this feature can be enabled through this method for appropriate WebAssembly modules.

This feature gates items such as the memory.copy instruction, passive data/table segments, etc, being in a module.

This is false by default.

pub fn multi_value(&mut self, enable: bool) -> &mut Features

Configures whether the WebAssembly multi-value proposal will be enabled.

The WebAssembly multi-value proposal is not currently fully standardized and is undergoing development. Support for this feature can be enabled through this method for appropriate WebAssembly modules.

This feature gates functions and blocks returning multiple values in a module, for example.

This is false by default.

Trait Implementations

impl Clone for Features

fn clone(&self) -> Features

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Features

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

Formats the value using the given formatter.

impl Default for Features

fn default() -> Features

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for Features

fn deserialize<__D>(
    __deserializer: __D
) -> Result<Features, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Eq for Features

impl PartialEq<Features> for Features

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for Features

fn serialize<__S>(
    &self,
    __serializer: __S
) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
