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 substrate_fixed::traits::FromFixed;
use substrate_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_value());
assert_eq!(i8::wrapping_from_fixed(f), 0x87u8 as i8);
assert_eq!(i8::overflowing_from_fixed(f), (0x87u8 as i8, true));

Required methods

fn from_fixed<F: Fixed>(src: F) -> Self

Converts from a fixed-point number.

Any extra fractional bits are truncated.

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.

fn checked_from_fixed<F: Fixed>(src: F) -> Option<Self> where
    Self: Sized, 

Converts from a fixed-point number if it fits, otherwise returns None.

Any extra fractional bits are truncated.

fn saturating_from_fixed<F: Fixed>(src: F) -> Self

Converts from a fixed-point number, saturating if it does not fit.

Any extra fractional bits are truncated.

fn wrapping_from_fixed<F: Fixed>(src: F) -> Self

Converts from a fixed-point number, wrapping if it does not fit.

Any extra fractional bits are truncated.

fn overflowing_from_fixed<F: Fixed>(src: F) -> (Self, bool) where
    Self: Sized, 

Converts from a fixed-point number.

Returns a tuple of the value and a bool indicating whether an overflow has occurred. On overflow, the wrapped value is returned.
