dynamic_vector_buffer::prepare

DynamicBuffer_v1: Get a list of buffers that represents the output sequence, with the given size.

mutable_buffers_type prepare(
    std::size_t n);

Ensures that the output sequence can accommodate n bytes, resizing the vector object as necessary.

Return Value

An object of type mutable_buffers_type that satisfies MutableBufferSequence requirements, representing vector memory at the start of the output sequence of size n.

Exceptions

std::length_error

If size() + n > max_size().

Remarks

The returned object is invalidated by any dynamic_vector_buffer or vector member function that modifies the input sequence or output sequence.
