Struct async_io_traits::io::Readiness

pub struct Readiness(_);

Expand description

Describes which operations are ready for an IO resource.

Implementations

impl Readiness

pub fn read(self) -> bool

The resource is ready to read from.

pub fn write(self) -> bool

The resource is ready to write to.

pub fn hup(self) -> bool

The resource has hung up.

Note there may still be data to read. Note that the user does not need to check this method, even if the resource has hung up, the behaviour of non_blocking_read and non_blocking_write is defined and they should not panic. Note that the user does not need to request an interest in hup notifications, they may always be returned
