pub struct Ready(/* private fields */);
Expand description
Describes the readiness state of an I/O resources.
Ready
tracks which operation an I/O resource is ready to perform.
Implementations§
source§impl Ready
impl Ready
sourcepub const READ_CLOSED: Ready = _
pub const READ_CLOSED: Ready = _
Returns a Ready
representing read closed readiness.
sourcepub const WRITE_CLOSED: Ready = _
pub const WRITE_CLOSED: Ready = _
Returns a Ready
representing write closed readiness.
sourcepub const PRIORITY: Ready = _
Available on Linux or Android only.
pub const PRIORITY: Ready = _
Returns a Ready
representing priority readiness.
sourcepub const ALL: Ready = _
Available on Linux or Android only.
pub const ALL: Ready = _
Returns a Ready
representing readiness for all operations.
sourcepub fn is_empty(self) -> bool
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());
sourcepub fn is_readable(self) -> bool
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());
sourcepub fn is_writable(self) -> bool
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());
sourcepub fn is_read_closed(self) -> bool
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());
sourcepub fn is_write_closed(self) -> bool
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());
sourcepub fn is_priority(self) -> bool
Available on Linux or Android only.
pub fn is_priority(self) -> bool
Returns true
if the value includes priority readiness
.
§Examples
use tokio::io::Ready;
assert!(!Ready::EMPTY.is_priority());
assert!(!Ready::WRITABLE.is_priority());
assert!(Ready::PRIORITY.is_priority());
