Struct tokio::io::Ready

pub struct Ready(_);

Describes the readiness state of an I/O resources.

Ready tracks which operation an I/O resource is ready to perform.

Implementations

impl Ready

pub const EMPTY: Ready

Returns the empty Ready set.

pub const READABLE: Ready

Returns a Ready representing readable readiness.

pub const WRITABLE: Ready

Returns a Ready representing writable readiness.

pub const READ_CLOSED: Ready

Returns a Ready representing read closed readiness.

pub const WRITE_CLOSED: Ready

Returns a Ready representing write closed readiness.

pub const ALL: Ready

Returns a Ready representing readiness for all operations.

pub fn is_empty(self) -> bool

Returns true if Ready is the empty set

Examples

use tokio::io::Ready;

assert!(Ready::EMPTY.is_empty());
assert!(!Ready::READABLE.is_empty());

pub fn is_readable(self) -> bool

Returns true if the value includes readable

Examples

use tokio::io::Ready;

assert!(!Ready::EMPTY.is_readable());
assert!(Ready::READABLE.is_readable());
assert!(Ready::READ_CLOSED.is_readable());
assert!(!Ready::WRITABLE.is_readable());

pub fn is_writable(self) -> bool

Returns true if the value includes writable readiness

Examples

use tokio::io::Ready;

assert!(!Ready::EMPTY.is_writable());
assert!(!Ready::READABLE.is_writable());
assert!(Ready::WRITABLE.is_writable());
assert!(Ready::WRITE_CLOSED.is_writable());

pub fn is_read_closed(self) -> bool

Returns true if the value includes read-closed readiness

Examples

use tokio::io::Ready;

assert!(!Ready::EMPTY.is_read_closed());
assert!(!Ready::READABLE.is_read_closed());
assert!(Ready::READ_CLOSED.is_read_closed());

pub fn is_write_closed(self) -> bool

Returns true if the value includes write-closed readiness

Examples

use tokio::io::Ready;

assert!(!Ready::EMPTY.is_write_closed());
assert!(!Ready::WRITABLE.is_write_closed());
assert!(Ready::WRITE_CLOSED.is_write_closed());
