Required Methods

unsafe fn push_unchecked(&mut self, value: T)

Will push an item and not check if there is enough capacity.

Safety

Caller must ensure the array has enough capacity to hold T.

unsafe fn extend_trusted_len_unchecked<I: IntoIterator<Item = T>>( &mut self, iter: I, )

Safety

Caller must ensure the iterators reported length is correct.

unsafe fn try_extend_trusted_len_unchecked<E, I: IntoIterator<Item = Result<T, E>>>( &mut self, iter: I, ) -> Result<(), E>

Safety

Caller must ensure the iterators reported length is correct.

unsafe fn from_trusted_len_iter_unchecked<I: IntoIterator<Item = T>>( iter: I, ) -> Self

Safety

Caller must ensure the iterators reported length is correct.

unsafe fn try_from_trusted_len_iter_unchecked<E, I: IntoIterator<Item = Result<T, E>>>( iter: I, ) -> Result<Self, E>

where Self: Sized,

Safety

Caller must ensure the iterators reported length is correct.

Provided Methods

fn extend_trusted_len<I: IntoIterator<Item = T, IntoIter = J>, J: TrustedLen>( &mut self, iter: I, )

Extend the array with an iterator who’s length can be trusted.

fn from_trusted_len_iter<I: IntoIterator<Item = T, IntoIter = J>, J: TrustedLen>( iter: I, ) -> Self

where Self: Sized,

fn try_from_trusted_len_iter<E, I: IntoIterator<Item = Result<T, E>, IntoIter = J>, J: TrustedLen>( iter: I, ) -> Result<Self, E>

where Self: Sized,

Object Safety

This trait is not object safe.
