Trait RangePattern 

pub trait RangePattern {
    const MIN: Self;
    const MAX: Self;

    // Required method
    fn sub_one(self) -> Self;
}

🔬This is a nightly-only experimental API. (pattern_type_range_trait)

A trait implemented for integer types and char. Useful in the future for generic pattern types, but used right now to simplify ast lowering of pattern type ranges.

Required Associated Constants

const MIN: Self

🔬This is a nightly-only experimental API. (pattern_type_range_trait)

Trait version of the inherent MIN assoc const.

const MAX: Self

🔬This is a nightly-only experimental API. (pattern_type_range_trait)

Trait version of the inherent MIN assoc const.

Required Methods

fn sub_one(self) -> Self

🔬This is a nightly-only experimental API. (pattern_type_range_trait)

A compile-time helper to subtract 1 for exclusive ranges.

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.
