}

A type that can hold Ts, and potentially reserve space for more Self::Itemss

Required methods

pub fn is_valid_storage() -> bool

Returns true if the this storage can hold types T

pub fn capacity(&self) -> usize

The number of elements that it is valid to write to this Storage

i.e. as_mut_ptr()..as_mut_ptr() + capacity() should be valid to write Ts

pub fn as_ptr(&self) -> *const T

Returns a pointer to the first element

pub fn as_mut_ptr(&mut self) -> *mut T

Returns a mutable pointer to the first element

pub fn reserve(&mut self, new_capacity: usize)

Reserves space for at least new_capacity elements

Safety

After this call successfully ends, the capacity must be at least new_capacity

Panic/Abort

Maybe panic or abort if it is impossible to set the capacity to at least new_capacity

pub fn try_reserve(&mut self, new_capacity: usize) -> Result<(), AllocError>

Tries to reserve space for at least new_capacity elements

Returns Ok(()) on success, Err(AllocError) if it is impossible to set the capacity to at least new_capacity

Safety

If Ok(()) is returned, the capacity must be at least new_capacity
