Struct wasihost_core::wasi_snapshot_preview1::Userdata

pub struct Userdata(pub userdata);

User-provided value that may be attached to objects that is retained when extracted from the implementation.

Trait Implementations

impl Clone for Userdata

fn clone(&self) -> Userdata

Returns a copy of the value.

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

impl Ord for Userdata

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Userdata> for Userdata

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

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

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

This method tests for !=.

impl PartialOrd<Userdata> for Userdata

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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