pub enum Abi {

}

Expand description

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

source

impl Abi

source

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.
