Enum WasiVersion

pub enum WasiVersion {
    Snapshot0,
    Snapshot1,
    Wasix32v1,
    Wasix64v1,
    Latest,
}

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

Variants

Snapshot0

wasi_unstable.

Snapshot1

wasi_snapshot_preview1.

Wasix32v1

wasix_32v1.

Wasix64v1

wasix_64v1.

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.

Implementations

impl WasiVersion

pub const fn get_namespace_str(&self) -> &'static str

Get the version as its namespace str as it appears in Wasm modules.

Trait Implementations

impl Clone for WasiVersion

fn clone(&self) -> WasiVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WasiVersion

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

Formats the value using the given formatter.

impl Ord for WasiVersion

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for WasiVersion

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

impl PartialOrd for WasiVersion

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
