### dynamic_string_buffer

Adapt a basic_string to the DynamicBuffer requirements.

    template<
        typename Elem,
        typename Traits,
        typename Allocator>
    class dynamic_string_buffer

##### Types

Name | Description
--- | ---
const_buffers_type | The type used to represent a sequence of constant buffers that refers to the underlying memory.
mutable_buffers_type | The type used to represent a sequence of mutable buffers that refers to the underlying memory.

##### Member Functions

Name | Description
--- | ---
capacity | Get the maximum size that the buffer may grow to without triggering reallocation.
commit | DynamicBuffer_v1: Move bytes from the output sequence to the input sequence.
consume | DynamicBuffer_v1: Remove characters from the input sequence. DynamicBuffer_v2: Consume the specified number of bytes from the beginning of the underlying memory.
data | DynamicBuffer_v1: Get a list of buffers that represents the input sequence. — DynamicBuffer_v2: Get a sequence of buffers that represents the underlying memory.
dynamic_string_buffer | Construct a dynamic buffer from a string. — DynamicBuffer_v2: Copy construct a dynamic buffer. — Move construct a dynamic buffer.
grow | DynamicBuffer_v2: Grow the underlying memory by the specified number of bytes.
max_size | Get the maximum size of the dynamic buffer.
prepare | DynamicBuffer_v1: Get a list of buffers that represents the output sequence, with the given size.
shrink | DynamicBuffer_v2: Shrink the underlying memory by the specified number of bytes.
size | DynamicBuffer_v1: Get the size of the input sequence. DynamicBuffer_v2: Get the current size of the underlying memory.

Requires that `sizeof(Elem) == 1`.
