Trait implementation for a pair in a QMap.

Required Associated Types

type Key

type Value

type TypeId

Required Methods

fn clear(map: &mut QMap<Self>)

fn clone(map: &QMap<Self>) -> QMap<Self>

fn contains(map: &QMap<Self>, key: &Self::Key) -> bool

fn default() -> QMap<Self>

fn drop(map: &mut QMap<Self>)

fn get_or_default(map: &QMap<Self>, key: &Self::Key) -> Self::Value

unsafe fn get_unchecked_key(map: &QMap<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(map: &QMap<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(map: &mut QMap<Self>, key: Self::Key, value: Self::Value)

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

fn insert_clone(map: &mut QMap<Self>, key: &Self::Key, value: &Self::Value)

fn len(map: &QMap<Self>) -> isize

fn remove(map: &mut QMap<Self>, key: &Self::Key) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
