Struct FPState

pub struct FPState {
    pub rounding_mode: RoundingMode,
    pub status_flags: StatusFlags,
    pub exception_handling_mode: ExceptionHandlingMode,
    pub tininess_detection_mode: TininessDetectionMode,
    /* private fields */
}

The dynamic state of a floating-point implementation

Fields

rounding_mode: RoundingMode

the dynamic rounding mode – used whenever the rounding mode is not explicitly overridden

status_flags: StatusFlags

the cumulative exception status flags

exception_handling_mode: ExceptionHandlingMode

the exception handling mode

tininess_detection_mode: TininessDetectionMode

the tininess detection mode

Implementations

impl FPState

pub fn checked_merge_assign( &mut self, rhs: Self, ) -> Result<(), FPStateMergeFailed>

combine two FPState values into one, assigning the result to self

pub fn merge_assign(&mut self, rhs: Self)

combine two FPState values into one, assigning the result to self

pub fn checked_merge(self, rhs: Self) -> Result<Self, FPStateMergeFailed>

combine two FPState values into one, returning the result

pub fn merge(self, rhs: Self) -> Self

combine two FPState values into one, returning the result

Trait Implementations

impl Clone for FPState

fn clone(&self) -> FPState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FPState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FPState

fn default() -> FPState

Returns the “default value” for a type.

impl Hash for FPState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FPState

fn eq(&self, other: &FPState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
