Struct pipebuf::PBufRdWr

pub struct PBufRdWr<'a, T: 'static = u8> {
    pub rd: PBufRd<'a, T>,
    pub wr: PBufWr<'a, T>,
}

Pair of consumer and producer references

Create this using the PipeBufPair::upper or PipeBufPair::lower calls, or equivalently PipeBufPair::left and PipeBufPair::right. Reborrow it using PBufRdWr::reborrow, or by reborrowing the members individually.

Fields

rd: PBufRd<'a, T>

Consumer reference for the incoming pipe

wr: PBufWr<'a, T>

Producer reference for the outgoing pipe

Implementations

impl<'a, T: Copy + Default + 'static> PBufRdWr<'a, T>

pub fn reborrow<'b, 'r>(&'r mut self) -> PBufRdWr<'b, T>

where 'a: 'b, 'r: 'b,

Create new references from these, reborrowing them. Thanks to the borrow checker, the original references will be inaccessible until the returned references’ lifetimes end. The cost is just a couple of pointer copies, just as for &mut reborrowing.

pub fn tripwire(&self) -> (PBufTrip, PBufTrip)

Generate tripwire values for both rd and wr halves of the pipe. See PBufTrip for more details.
