[−]Struct wasi_types::OpenFlags
Methods
impl OpenFlags
pub const CREATE: OpenFlags
Create file if it does not exist.
pub const DIRECTORY: OpenFlags
Fail if not a directory.
pub const EXCL: OpenFlags
Fail if file already exists.
pub const TRUNC: OpenFlags
Truncate file to size 0.
pub const fn empty() -> OpenFlags
Returns an empty set of flags
pub const fn all() -> OpenFlags
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<OpenFlags>
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) -> OpenFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u16) -> OpenFlags
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: OpenFlags) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: OpenFlags) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: OpenFlags)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: OpenFlags)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: OpenFlags)
Toggles the specified flags in-place.
pub fn set(&mut self, other: OpenFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
