Struct PollResponse

pub struct PollResponse { /* private fields */ }

Represents the bitmask of event flags produced for a PollRequest when passed to poll.

Implementations

impl PollResponse

pub const fn raw_result(&self) -> c_short

Returns the raw bitmask representing the events that the kernel reported. The meaning of this bitmask may be architecture-dependent.

pub const fn readable(&self) -> bool

Returns true if the response indicates that there is data to read.

pub const fn writable(&self) -> bool

Returns true if the response indicates that the file is writable.

This only indicates that some amount of writing is possible, but does not guarantee that a write of any given size will succeed.

pub const fn error(&self) -> bool

Returns true if there is an error condition on the file descriptor.

This condition is also used for the write end of a pipe once the read end has been closed.

pub const fn hung_up(&self) -> bool

Returns true if the other end of a channel has been closed.

There might still be data in the read buffer, which can be read until reaching EOF.

pub const fn exception(&self) -> bool

Returns true if there is an exceptional condition on the file descriptor.

pub const fn invalid(&self) -> bool

Returns true if the kernel deemed the corresponding request to be invalid.
