Struct AdapterOptions

pub struct AdapterOptions {
    pub instance: RuntimeComponentInstanceIndex,
    pub string_encoding: StringEncoding,
    pub memory: Option<CoreExport<MemoryIndex>>,
    pub memory64: bool,
    pub realloc: Option<CoreDef>,
    pub callback: Option<CoreDef>,
    pub post_return: Option<CoreDef>,
    pub async_: bool,
}

Configuration options which can be specified as part of the canonical ABI in the component model.

Fields

instance: RuntimeComponentInstanceIndex

The Wasmtime-assigned component instance index where the options were originally specified.

string_encoding: StringEncoding

How strings are encoded.

memory: Option<CoreExport<MemoryIndex>>

An optional memory definition supplied.

memory64: bool

If memory is specified, whether it’s a 64-bit memory.

realloc: Option<CoreDef>

An optional definition of realloc to used.

callback: Option<CoreDef>

The async callback function used by these options, if specified.

post_return: Option<CoreDef>

An optional definition of a post-return to use.

async_: bool

Whether to use the async ABI for lifting or lowering.

Trait Implementations

impl Clone for AdapterOptions

fn clone(&self) -> AdapterOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AdapterOptions

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

Formats the value using the given formatter.

impl Hash for AdapterOptions

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AdapterOptions

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