Enum witx::Abi

pub enum Abi {
    Preview1,
}

Possible ABIs for interface functions to have.

Note that this is a stopgap until we have more of interface types. Interface types functions do not have ABIs, they have APIs. For the meantime, however, we mandate ABIs to ensure we can all talk to each other.

Variants

Preview1

Only stable ABI currently, and is the historical WASI ABI since it was first created.

Note that this ABI is limited notably in its return values where it can only return 0 results or one Result<T, enum> lookalike.

Implementations

impl Abi

pub fn validate(
    &self,
    _params: &[InterfaceFuncParam],
    results: &[InterfaceFuncParam]
) -> Result<(), String>

Validates the parameters/results are representable in this ABI.

Returns an error string if they’re not representable or returns Ok if they’re indeed representable.

Trait Implementations

impl Clone for Abi

fn clone(&self) -> Abi

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Abi

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

Formats the value using the given formatter.

impl Hash for Abi

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Abi> for Abi

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

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