Integer

Enum Integer 

Source
pub enum Integer {
    Signed(i64),
    Unsigned(u64),
}
Expand description

A property-list integer, carrying its signedness.

Plists must represent both u64::MAX and negative values, so the model is the pair of a raw 64-bit payload and a sign flag rather than a single i64. Equality, ordering, and hashing are numeric: no codec preserves signedness for non-negative values, so Signed(5) and Unsigned(5) are the same integer (and hash identically).

§Examples

use apple_plist::Integer;

assert_eq!(Integer::from(5i64), Integer::from(5u64));
assert!(Integer::from(-1i8) < Integer::from(0u8));

Variants§

§

Signed(i64)

A signed value; the only representation negative integers have.

§

Unsigned(u64)

An unsigned value, covering i64::MAX + 1 ..= u64::MAX exclusively.

Implementations§

Source§

impl Integer

Source

pub const fn as_signed(self) -> Option<i64>

Returns the value as an i64 when it fits.

§Examples
use apple_plist::Integer;

assert_eq!(
    Integer::Unsigned(i64::MAX as u64).as_signed(),
    Some(i64::MAX)
);
assert_eq!(Integer::Unsigned(i64::MAX as u64 + 1).as_signed(), None);
assert_eq!(Integer::Signed(-1).as_signed(), Some(-1));
Source

pub const fn as_unsigned(self) -> Option<u64>

Returns the value as a u64 when it is non-negative.

§Examples
use apple_plist::Integer;

assert_eq!(Integer::Signed(0).as_unsigned(), Some(0));
assert_eq!(Integer::Signed(-1).as_unsigned(), None);
assert_eq!(Integer::Unsigned(u64::MAX).as_unsigned(), Some(u64::MAX));
