fmt::basic_memory_buffer

A dynamically growing memory buffer for trivially copyable/constructible types with the first SIZE elements stored in the object itself. Most commonly used via the memory_buffer alias for char.

Synopsis

Declared in <fmt/format.h>

template<
    typename T,
    size_t SIZE = inline_buffer_size,
    typename Allocator = /* implementation-defined */>
class basic_memory_buffer
    : public /* implementation-defined */

Base Classes

Name	Description
`/* implementation-defined */`	A contiguous memory buffer with an optional growing ability. It is an internal class and shouldn't be used directly, only via `memory_buffer`.

Types

Name
`const_reference`
`value_type`

Member Functions

Name	Description
`basic_memory_buffer` [constructor]	Constructs a `basic_memory_buffer` object moving the content of the other object to it.
`~basic_memory_buffer` [destructor]	Destructor
`operator=`	Moves the content of the other `basic_memory_buffer` object to this one.
`append`
`get_allocator`
`reserve`	Increases the buffer capacity to `new_capacity`.
`resize`	Resizes the buffer to contain `count` elements. If T is a POD type new elements may not be initialized.

Description

Example:

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