[−]Struct wasi_types::FdFlags
Methods
impl FdFlags
pub const APPEND: FdFlags
Append mode: Data written to the file is always appended to the file's end.
pub const DSYNC: FdFlags
Write according to synchronized I/O data integrity completion. Only the data stored in the file is synchronized.
pub const NONBLOCK: FdFlags
Non-blocking mode.
pub const RSYNC: FdFlags
Synchronized read I/O operations.
pub const SYNC: FdFlags
Write according to synchronized I/O file integrity completion. In addition to synchronizing the data stored in the file, the implementation may also synchronously update the file's metadata.
pub const fn empty() -> FdFlags
Returns an empty set of flags
pub const fn all() -> FdFlags
Returns the set containing all flags.
pub const fn bits(&self) -> u16
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u16) -> Option<FdFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: u16) -> FdFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u16) -> FdFlags
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
pub const fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub const fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub const fn intersects(&self, other: FdFlags) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: FdFlags) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: FdFlags)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: FdFlags)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: FdFlags)
Toggles the specified flags in-place.
pub fn set(&mut self, other: FdFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
