Trait Implementations

impl AsRef<Predicate> for Predicate

fn as_ref(&self) -> &Predicate

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

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

Formats the value using the given formatter.

impl Display for Predicate

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

Formats the value using the given formatter.

impl FromStr for Predicate

type Err = Token

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Predicate

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, 

Feeds a slice of this type into the given Hasher.

impl PartialEq<Predicate> for Predicate

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

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

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

This method tests for !=.
