Struct PointerArray

pub struct PointerArray<'a, const N: usize = 4> { /* private fields */ }

Implementations

impl<'a, const N: usize> PointerArray<'a, N>

pub const fn new() -> Self

Construct an empty PointerArray.

Array have a length of 4usize by default.

impl<'a, const N: usize> PointerArray<'a, N>

pub fn insert_mut<'b, T: 'static>( self, value: &'b mut T, ) -> Result<PointerArray<'b, N>, Full<'a, N>>

where 'a: 'b,

Insert a &mut T to array. This method would consume Self.

If the array have a &mut T already it would replace it and the old one is dropped. *. only the &mut T would be dropped and destructor of T does not run.

On Ok(Self) the array with reference successfully inserted would returned. (Self’s lifetime is shrink to the same of input &mut T).

On Err(Full) the array without modification would be returned. See Full::into_inner for detail.

pub fn insert_ref<'b, T: 'static>( self, value: &'b T, ) -> Result<PointerArray<'b, N>, Full<'a, N>>

where 'a: 'b,

The &T version of Self::insert_mut. See it for more detail.

pub fn remove_ref<T: 'static>(&mut self) -> Option<&'a T>

&T version of Self::remove_mut. See it for detail.

pub fn remove_mut<T: 'static>(&mut self) -> Option<&'a mut T>

Remove &mut T from array. Return None when there is no according type in array.

pub fn get<T: 'static>(&self) -> Option<&'a T>

Get &T without removing it from the array.

&T can be get from either insert with Self::insert_mut or Self::insert_ref.

pub fn get_mut<T: 'static>(&mut self) -> Option<&'a mut T>

Get &mut T without removing it from the array.

&mut T can be get from insert with Self::insert_mut.

fn default() -> Self

Returns the “default value” for a type.
