Enum AbiVariant

pub enum AbiVariant {
    GuestImport,
    GuestExport,
}

We use a different ABI for wasm importing functions exported by the host than for wasm exporting functions imported by the host.

Note that this reflects the flavor of ABI we generate, and not necessarily the way the resulting bindings will be used by end users. See the comments on the Direction enum in gen-core for details.

The bindings ABI has a concept of a “guest” and a “host”. There are two variants of the ABI, one specialized for the “guest” importing and calling a function defined and exported in the “host”, and the other specialized for the “host” importing and calling a function defined and exported in the “guest”.

Variants

GuestImport

The guest is importing and calling the function.

GuestExport

The guest is defining and exporting the function.

Trait Implementations

impl Clone for AbiVariant

fn clone(&self) -> AbiVariant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AbiVariant

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

Formats the value using the given formatter.

impl PartialEq for AbiVariant

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