Implementations

impl WherePredicate

pub(crate) fn get_bounds(&self) -> Option<&[GenericBound]>

Trait Implementations

impl Clone for WherePredicate

fn clone(&self) -> WherePredicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WherePredicate

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

Formats the value using the given formatter.

impl FromClean<WherePredicate> for WherePredicate

fn from_clean(predicate: WherePredicate, renderer: &JsonRenderer<'_>) -> Self

impl Hash for WherePredicate

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WherePredicate

fn eq(&self, other: &WherePredicate) -> 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 Eq for WherePredicate

impl StructuralPartialEq for WherePredicate

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.
