Detailed Description

template<typename T, usize N>
class lib::static_vector< T, N >

A contiguous sequence of up to N elements stored entirely.

Template Parameters

T	Element type.
N	Maximum number of elements.

Member Function Documentation

pop_back()

template<typename T, usize N>

auto lib::static_vector< T, N >::pop_back ( ) ->void

inlineexportnoexcept

Remove and destroy the last element.

Note

No-op if empty.

push_back()

template<typename T, usize N>

auto lib::static_vector< T, N >::push_back ( const T & val ) ->std::expected< void, lib::kernel_error >

inlineexportnoexcept

Append a copy of val.

Returns

expected<void, kernel_error>: err(generic::out_of_range) when full.

push_back_unchecked()

template<typename T, usize N>

auto lib::static_vector< T, N >::push_back_unchecked ( const T & val ) ->void

inlineexportnoexcept

Unchecked push — caller guarantees !full().

Warning

Undefined behavior if full().
