Struct rustc_apfloat::Status [−]
#[must_use]pub struct Status { /* fields omitted */ }
IEEE-754R 7: Default exception handling.
UNDERFLOW or OVERFLOW are always returned or-ed with INEXACT.
Methods

pub fn empty() -> Status
pub fn empty() -> Status
Returns an empty set of flags.
pub fn all() -> Status
pub fn all() -> Status
Returns the set containing all flags.
pub fn bits(&self) -> u8
pub fn bits(&self) -> u8
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u8) -> Option<Status>
pub fn from_bits(bits: u8) -> Option<Status>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub fn from_bits_truncate(bits: u8) -> Status
pub fn from_bits_truncate(bits: u8) -> Status
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
pub fn is_all(&self) -> bool
pub fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub fn intersects(&self, other: Status) -> bool
pub fn intersects(&self, other: Status) -> bool
Returns true
if there are flags common to both self
and other
.
pub fn contains(&self, other: Status) -> bool
pub fn contains(&self, other: Status) -> bool
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: Status)
pub fn insert(&mut self, other: Status)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: Status)
pub fn remove(&mut self, other: Status)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: Status)
pub fn toggle(&mut self, other: Status)

pub fn set(&mut self, other: Status, value: bool)
pub fn set(&mut self, other: Status, value: bool)
