Struct wasihost_core::wasi_snapshot_preview1::Fdflags

pub struct Fdflags { /* fields omitted */ }

File descriptor flags.

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.
