Expand description
This trait provides checked conversions from fixed-point numbers.
This trait is implemented for conversions between integer primitives, floating-point primitives and fixed-point numbers.
Examples
use fixed::traits::FromFixed;
use fixed::types::U8F8;
// 0x87.65
let f = U8F8::from_bits(0x8765);
assert_eq!(f32::from_fixed(f), f32::from(0x8765u16) / 256.0);
assert_eq!(i32::checked_from_fixed(f), Some(0x87));
assert_eq!(u8::saturating_from_fixed(f), 0x87);
// no fit
assert_eq!(i8::checked_from_fixed(f), None);
assert_eq!(i8::saturating_from_fixed(f), i8::MAX);
assert_eq!(i8::wrapping_from_fixed(f), 0x87u8 as i8);

Required Methods
fn from_fixed<F: Fixed>(src: F) -> Self
fn from_fixed<F: Fixed>(src: F) -> Self
Converts from a fixed-point number.
Any extra fractional bits are discarded, which rounds towards −∞.

not fit. When debug assertions are not enabled, the wrapped
value can be returned, but it is not considered a breaking
change if in the future it panics; if wrapping is required use
wrapping_from_fixed
instead.

Converts a fixed-point number to a floating-point number, saturating if it does not fit.
Rounding is to the nearest, with ties rounded to even.
sourcefn wrapping_from_fixed<F: Fixed>(src: F) -> Self
fn wrapping_from_fixed<F: Fixed>(src: F) -> Self
Converts a fixed-point number to a floating-point number, wrapping if it does not fit.
Rounding is to the nearest, with ties rounded to even.
sourcefn overflowing_from_fixed<F: Fixed>(src: F) -> (Self, bool)
fn overflowing_from_fixed<F: Fixed>(src: F) -> (Self, bool)
sourcefn unwrapped_from_fixed<F: Fixed>(src: F) -> Self
fn unwrapped_from_fixed<F: Fixed>(src: F) -> Self
Converts a fixed-point number to a floating-point number, panicking if it does not fit.
Rounding is to the nearest, with ties rounded to even.
Panics
Panics if the value does not fit, even when debug assertions are not enabled.

impl FromFixed for f32
sourcefn from_fixed<F: Fixed>(src: F) -> Self
fn from_fixed<F: Fixed>(src: F) -> Self
Converts a fixed-point number to a floating-point number.
Rounding is to the nearest, with ties rounded to even.
Panics
When debug assertions are enabled, panics if the value
does not fit. When debug assertions are not enabled,
the wrapped value can be returned, but it is not
considered a breaking change if in the future it
panics; if wrapping is required use
wrapping_from_fixed
instead.
sourcefn checked_from_fixed<F: Fixed>(src: F) -> Option<Self>
fn checked_from_fixed<F: Fixed>(src: F) -> Option<Self>
Converts a fixed-point number to a floating-point
number if it fits, otherwise returns None
.
Rounding is to the nearest, with ties rounded to even.
