Detailed Description

template<typename T, size_t SIZE = inline_buffer_size, typename Allocator = std::allocator<T>>
class basic_memory_buffer< T, SIZE, Allocator >

A dynamically growing memory buffer for trivially copyable/constructible types with the first SIZE elements stored in the object itself.

You can use one of the following type aliases for common character types:

+-------------—+---------------------------—+ | Type | Definition | +================+==============================+ | memory_buffer | basic_memory_buffer<char> | +-------------—+---------------------------—+ | wmemory_buffer | basic_memory_buffer<wchar_t> | +-------------—+---------------------------—+

Example**::

fmt::memory_buffer out; format_to(out, "The answer is {}.", 42);

This will append the following output to the out object:

.. code-block:: none

The answer is 42.

The output can be converted to an std::string with to_string(out).

Constructor & Destructor Documentation

basic_memory_buffer()

template<typename T, size_t SIZE = inline_buffer_size, typename Allocator = std::allocator<T>>

basic_memory_buffer< T, SIZE, Allocator >::basic_memory_buffer ( basic_memory_buffer< T, SIZE, Allocator > &&  other )

inline

Constructs a :class:fmt::basic_memory_buffer object moving the content of the other object to it.

Member Function Documentation

grow()

template<typename T , size_t SIZE, typename Allocator >

void basic_memory_buffer< T, SIZE, Allocator >::grow ( size_t  capacity )

finalprotectedvirtual

Increases the buffer capacity to hold at least capacity elements.

Implements detail::buffer< T >.

operator=()

template<typename T, size_t SIZE = inline_buffer_size, typename Allocator = std::allocator<T>>

basic_memory_buffer& basic_memory_buffer< T, SIZE, Allocator >::operator= ( basic_memory_buffer< T, SIZE, Allocator > &&  other )

inline

Moves the content of the other basic_memory_buffer object to this one.

reserve()

template<typename T, size_t SIZE = inline_buffer_size, typename Allocator = std::allocator<T>>

void basic_memory_buffer< T, SIZE, Allocator >::reserve ( size_t  new_capacity )

inline

Increases the buffer capacity to new_capacity.

resize()

template<typename T, size_t SIZE = inline_buffer_size, typename Allocator = std::allocator<T>>

void basic_memory_buffer< T, SIZE, Allocator >::resize ( size_t  count )

inline

Resizes the buffer to contain count elements.

If T is a POD type new elements may not be initialized.
