Implementations

impl Num

pub fn to_u32(self) -> Option<u32>

Converts self into a u32 if self is an unsigned variant with <= 32 bits.

Example

use figment::value::Num;

let num: Num = 123u8.into();
assert_eq!(num.to_u32(), Some(123));

let num: Num = (u32::max_value() as u64 + 1).into();
assert_eq!(num.to_u32(), None);

pub fn to_u128(self) -> Option<u128>

Converts self into a u128 if self is an unsigned variant.

Example

use figment::value::Num;

let num: Num = 123u8.into();
assert_eq!(num.to_u128(), Some(123));

pub fn to_i128(self) -> Option<i128>

Converts self into a u128 if self is an unsigned Value::Num variant.

Example

use figment::value::Num;

let num: Num = 123i8.into();
assert_eq!(num.to_i128(), Some(123));

pub fn to_actual(&self) -> Actual

Converts self into an Actual. All unsigned variants return Actual::Unsigned, signed variants Actual::Signed, and float variants Actual::Float. Values exceeding the bit-width of the target Actual are truncated.

Example

use figment::{value::Num, error::Actual};

assert_eq!(Num::U8(10).to_actual(), Actual::Unsigned(10));
assert_eq!(Num::U64(2380).to_actual(), Actual::Unsigned(2380));

assert_eq!(Num::I8(127).to_actual(), Actual::Signed(127));
assert_eq!(Num::ISize(23923).to_actual(), Actual::Signed(23923));

assert_eq!(Num::F32(2.5).to_actual(), Actual::Float(2.5));
assert_eq!(Num::F64(2.103).to_actual(), Actual::Float(2.103));
