Expand description

The ‘RxBuffer’ is a used when reading data in. The contents of the buffer can be uninitialized.

Required methods

The allocated size

Returns a void*/size_t pair to be used in the C call.

Returns a char*/size_t pair to be used in the C call.

After the reading operation is done the buffer must be sealed with the actual length of the data retrieved. This function returns a slice into the buffer containing the data.

Provided methods

Get a ‘Some(ResizeableBuffer)’ when the underlying Buffer supports allocating more memory
