Trait implementation for a pair in a QHash.

Required Associated Types

type Key

type Value

type TypeId

Required Methods

fn clear(hash: &mut QHash<Self>)

fn clone(hash: &QHash<Self>) -> QHash<Self>

fn contains(hash: &QHash<Self>, key: &Self::Key) -> bool

fn default() -> QHash<Self>

fn drop(hash: &mut QHash<Self>)

fn get_or_default(hash: &QHash<Self>, key: &Self::Key) -> Self::Value

unsafe fn get_unchecked_key(hash: &QHash<Self>, pos: isize) -> &Self::Key

Safety

Calling this method with an out-of-bounds index is undefined behavior even if the resulting reference is not used.

unsafe fn get_unchecked_value(hash: &QHash<Self>, pos: isize) -> &Self::Value

Safety

Calling this method with an out-of-bounds index is undefined behavior even if the resulting reference is not used.

fn insert(hash: &mut QHash<Self>, key: Self::Key, value: Self::Value)

where Self::Key: ExternType<Kind = Trivial>, Self::Value: ExternType<Kind = Trivial>,

fn insert_clone(hash: &mut QHash<Self>, key: &Self::Key, value: &Self::Value)

fn len(hash: &QHash<Self>) -> isize

fn remove(hash: &mut QHash<Self>, key: &Self::Key) -> bool

Object Safety

This trait is not object safe.
