Enum QuietNaNFormat

#[repr(u8)]
pub enum QuietNaNFormat {
    Standard = 0,
    MIPSLegacy = 1,
}

the format for quiet NaN values

IEEE 754 states that implementations should use the MSB of the mantissa being set to indicate a quiet NaN, however MIPS before the 2008 revision and PA-RISC use the MSB of the mantissa being clear to indicate a quiet NaN.

Variants

Standard = 0

MSB of mantissa set to indicate quiet NaN

MIPSLegacy = 1

MSB of mantissa clear to indicate quiet NaN; also used in PA-RISC

Implementations

impl QuietNaNFormat

pub fn is_nan_quiet(self, mantissa_msb_set: bool) -> bool

returns true if a NaN with the mantissa MSB set to mantissa_msb_set is a quiet NaN

Trait Implementations

impl Clone for QuietNaNFormat

fn clone(&self) -> QuietNaNFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuietNaNFormat

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

Formats the value using the given formatter.

impl Default for QuietNaNFormat

fn default() -> QuietNaNFormat

Returns the “default value” for a type.

impl Hash for QuietNaNFormat

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 QuietNaNFormat

fn eq(&self, other: &QuietNaNFormat) -> 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.
