Enum wasmer_c_api::wasm_c_api::wasi::wasi_version_t

#[repr(C)]
pub enum wasi_version_t {
    INVALID_VERSION,
    LATEST,
    SNAPSHOT0,
    SNAPSHOT1,
    WASIX32V1,
    WASIX64V1,
}

The version of WASI. This is determined by the imports namespace string.

Variants

INVALID_VERSION

An invalid version.

LATEST

Latest version.

It’s a “floating” version, i.e. it’s an alias to the latest version (for the moment, Snapshot1). Using this version is a way to ensure that modules will run only if they come with the latest WASI version (in case of security issues for instance), by just updating the runtime.

Note that this version is never returned by an API. It is provided only by the user.

SNAPSHOT0

wasi_unstable.

SNAPSHOT1

wasi_snapshot_preview1.

WASIX32V1

wasix_32v1.

WASIX64V1

wasix_64v1.

Trait Implementations

impl Clone for wasi_version_t

fn clone(&self) -> wasi_version_t

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for wasi_version_t

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

Formats the value using the given formatter.

impl From<WasiVersion> for wasi_version_t

fn from(other: WasiVersion) -> Self

Converts to this type from the input type.

impl PartialEq<wasi_version_t> for wasi_version_t

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<wasi_version_t> for WasiVersion

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(other: wasi_version_t) -> Result<Self, Self::Error>

Performs the conversion.
