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. Most commonly used via the memory_buffer alias for char.

Example:

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

This will append "The answer is 42." to out. The buffer content can be converted to 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>>

FMT_CONSTEXPR20 basic_memory_buffer< T, SIZE, Allocator >::basic_memory_buffer ( basic_memory_buffer< T, SIZE, Allocator > && other )

inlinenoexcept

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

Member Function Documentation

resize()

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

FMT_CONSTEXPR20 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.
