Detailed Description

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

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

You can use the memory_buffer type alias for char instead.

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). \endrst

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

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

Member Function Documentation

operator=()

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

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

inline

\rst Moves the content of the other basic_memory_buffer object to this one. \endrst

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.
