Trait narrow::offset::OffsetElement

pub trait OffsetElement: FixedSize + AddAssign + Default + TryFrom<usize, Error = TryFromIntError> + TryInto<usize, Error = TryFromIntError> + Sub<Output = Self> + Sealed + 'static {
    type Unsigned: TryFrom<usize, Error = TryFromIntError>;

    // Required methods
    fn checked_add(self, rhs: Self) -> Option<Self>;
    fn checked_add_unsigned(self, rhs: Self::Unsigned) -> Option<Self>;
}

Types representing offset values.

Values with these types can be used to represent offset values.

This trait is sealed to prevent downstream implementations.

Required Associated Types

type Unsigned: TryFrom<usize, Error = TryFromIntError>

The unsigned variant of Self.

Required Methods

fn checked_add(self, rhs: Self) -> Option<Self>

Checked addition. Computes self + rhs, returning None if overflow occurred.

fn checked_add_unsigned(self, rhs: Self::Unsigned) -> Option<Self>

Checked addition with an unsigned value. Computes self + rhs, returning None if overflow occurred.

Object Safety

This trait is not object safe.
