Struct Status 

pub struct Status(/* private fields */);

What a conversion had to do to the number to fit it in the format.

A bitmask, so that one conversion can report several. The names are IEEE 754’s exceptions, which is what the diagnostics are ultimately about: GCC warns that a floating constant exceeds the range of its type, or that it was truncated to zero.

Implementations

impl Status

pub const NONE: Status

The value is exactly what was written.

pub const INEXACT: Status

The value had to be rounded, so it is not what was written.

pub const OVERFLOW: Status

The value is too large for the format and became an infinity.

pub const UNDERFLOW: Status

The value is too small for the format and became a subnormal or a zero.

pub const INVALID: Status

The operation has no answer at all, such as an infinity minus an infinity.

pub const DIVIDE_BY_ZERO: Status

A number that is not zero was divided by one that is, so the answer is an infinity.

pub const fn has(self, other: Status) -> bool

Whether every flag in other is set here.

pub const fn with(self, other: Status) -> Status

This set with other added.

pub const fn is_none(self) -> bool

Whether nothing happened to the number.
