impl<'tcx> Debug for OutlivesConstraint<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Ord for OutlivesConstraint<'tcx>

fn cmp(&self, other: &OutlivesConstraint<'tcx>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl<'tcx> PartialEq<OutlivesConstraint<'tcx>> for OutlivesConstraint<'tcx>

fn eq(&self, other: &OutlivesConstraint<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &OutlivesConstraint<'tcx>) -> bool

This method tests for !=.

impl<'tcx> PartialOrd<OutlivesConstraint<'tcx>> for OutlivesConstraint<'tcx>

fn partial_cmp(&self, other: &OutlivesConstraint<'tcx>) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
