Struct stack_graphs::arena::Handle

pub struct Handle<T> { /* fields omitted */ }

A handle to an instance of type T that was allocated from an Arena.

Safety

Because of the type parameter T, the compiler can ensure that you don’t use a handle for one type to index into an arena of another type. However, if you have multiple arenas for the same type, we do not do anything to ensure that you only use a handle with the corresponding arena.

Trait Implementations

impl<T> Ord for Handle<T>

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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