Fields
name: String
module: Option<String>
The module name to use for bindings generation.
If None
, then the interface name will be used.
If Some
, then this value is used to format an export
name of <module>#<name>
for exports or an import module
name of <module>
for imports.

Implementations
sourceimpl Interface
impl Interface
sourcepub fn wasm_signature(
&self,
variant: AbiVariant,
func: &Function
) -> WasmSignature
pub fn wasm_signature(
&self,
variant: AbiVariant,
func: &Function
) -> WasmSignature
Get the WebAssembly type signature for this interface function
The first entry returned is the list of parameters and the second entry is the list of results for the wasm function signature.
sourcepub fn call(
&self,
variant: AbiVariant,
lift_lower: LiftLower,
func: &Function,
bindgen: &mut impl Bindgen
)
pub fn call(
&self,
variant: AbiVariant,
lift_lower: LiftLower,
func: &Function,
bindgen: &mut impl Bindgen
)
Generates an abstract sequence of instructions which represents this function being adapted as an imported function.
The instructions here, when executed, will emulate a language with
interface types calling the concrete wasm implementation. The parameters
for the returned instruction sequence are the language’s own
interface-types parameters. One instruction in the instruction stream
will be a Call
which represents calling the actual raw wasm function
signature.
This function is useful, for example, if you’re building a language generator for WASI bindings. This will document how to translate language-specific values into the wasm types to call a WASI function, and it will also automatically convert the results of the WASI function back to a language-specific value.
