Crate dyn_buf[][src]

Expand description

A dynamic buffer encapsulates memory storage that may be automatically resized as required, where the memory is divided into two regions: readable bytes followed by writable bytes. These memory regions are internal to the dynamic buffer, but direct access to the elements is provided to permit them to be efficiently used with I/O operations.

Note: Such as the send or receive operations of a socket. The readable bytes would be used as
the constant buffer sequence for send, and the writable bytes used as the mutable buffer
sequence for receive.

Data written to the writable bytes of a dynamic buffer object is appended to the readable bytes of the same object.


VecBuf is an effective dynamic buffer v1 implement, which tries to reduce reallocation and mem-moving.
