Trait RangeOps

pub trait RangeOps<'a>:
    Debug
    + Ord
    + PartialOrd
    + Eq
    + PartialEq
    + TryFrom<Datum<'a>>
    + Into<Datum<'a>>
where
    <Self as TryFrom<Datum<'a>>>::Error: Debug,
{
    // Required method
    fn err_type_name() -> &'static str;

    // Provided methods
    fn step(self) -> Option<Self> { ... }
    fn unwrap_datum(d: Datum<'a>) -> Self { ... }
}

Trait alias for traits required for generic range function implementations.

Required Methods

fn err_type_name() -> &'static str

Provided Methods

fn step(self) -> Option<Self>

Increment self one step forward, if applicable. Return None if overflows.

fn unwrap_datum(d: Datum<'a>) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
