Struct tk_bufstream::MockData [] [src]

pub struct MockData { /* fields omitted */ }

A mock stream where you can push data to/from

Useful for more complex tests on streams than are possible with Mock

Methods

impl MockData
[src]

New, empty Mockdata

Add some bytes to the next input. This data will be read by IoBuf on thext read() call

Get slice of output

Note: we only read bytes that has been write'en here, not the bytes buffered inside IoBuf.

Note 2: we use RangeArgument from netbuf here, as we already depend on netbuf anyway. Eventually we will switch to RangeArgument from std (both in netbuf and here) when latter is stable.

Get first bytes of output and remove them from output buffer

Note: we only read bytes that has been write'en here, not the bytes buffered inside IoBuf.
