Enum PointerEquality

pub enum PointerEquality {
    ForbidAll,
    AllowNested,
    AllowAll,
}

Controls what kind of by-pointer equality comparison is allowed.

See //snix/docs/value-pointer-equality.md for details.

Variants

ForbidAll

Pointer equality not allowed at all.

AllowNested

Pointer equality comparisons only allowed for nested values.

AllowAll

Pointer equality comparisons are allowed in all contexts.

Trait Implementations

impl Clone for PointerEquality

fn clone(&self) -> PointerEquality

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PointerEquality

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for PointerEquality

fn cmp(&self, other: &PointerEquality) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PointerEquality

fn eq(&self, other: &PointerEquality) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PointerEquality

fn partial_cmp(&self, other: &PointerEquality) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
