Struct decimal::Status
[−]
pub struct Status { /* fields omitted */ }
The status of the floating point context. Instead of faulting after every operation errors are added to this status. User code can check and/or clear the status fully or partially at specific points to check the validity of the computation. Each thread gets its own status. The status is initially empty.
Examples
assert_eq!(d128::get_status(), Status::empty()); let _ = d128!(1) / &d128!(0); assert!(d128::get_status().contains(decimal::Status::DIVISION_BY_ZERO)); let _ = d128!(0) / &d128!(0); assert!(d128::get_status().contains(decimal::Status::DIVISION_UNDEFINED)); // The previous status flag was not cleared! assert!(d128::get_status().contains(decimal::Status::DIVISION_BY_ZERO));
Methods
impl Status
const CONVERSION_SYNTAX: Status
CONVERSION_SYNTAX: Status = Status{bits: 1,}

const DIVISION_UNDEFINED: Status
DIVISION_UNDEFINED: Status = Status{bits: 8,}
Division undefined.
const INEXACT: Status
INEXACT: Status = Status{bits: 32,}
The result is inexact.
const INVALID_OPERATION: Status
INVALID_OPERATION: Status = Status{bits: 128,}
An invalid operation was requested.
const OVERFLOW: Status
OVERFLOW: Status = Status{bits: 512,}
Overflow.
const UNDERFLOW: Status
UNDERFLOW: Status = Status{bits: 8192,}
Underflow.
fn empty() -> Status
Returns an empty set of flags.
fn all() -> Status
Returns the set containing all flags.
fn bits(&self) -> uint32_t
Returns the raw value of the flags currently stored.
fn from_bits(bits: uint32_t) -> Option<Status>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: uint32_t) -> Status
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
fn is_all(&self) -> bool
Returns true
if all flags are currently set.
fn intersects(&self, other: Status) -> bool
Returns true
if there are flags common to both self
and other
.
fn contains(&self, other: Status) -> bool
Returns true
all of the flags in other
are contained within self
.
fn insert(&mut self, other: Status)
Inserts the specified flags in-place.
fn remove(&mut self, other: Status)
Removes the specified flags in-place.
fn toggle(&mut self, other: Status)
Toggles the specified flags in-place.
fn set(&mut self, other: Status, value: bool)
Inserts or removes the specified flags depending on the passed value.
