Trait Implementations

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<'de, R: Reader<'de, _Ptr, _Any>> Deserialize<'de, IOValue, IOValue, R> for Predicate

fn deserialize(r: &mut R) -> Result<Self, ParseError>

impl From<&'_ Predicate> for _Any

fn from(value: &Predicate) -> Self

Performs the conversion.

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 Ord for Predicate

fn cmp(&self, other: &Predicate) -> 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 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 !=.

impl PartialOrd<Predicate> for Predicate

fn partial_cmp(&self, other: &Predicate) -> 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.

impl TryFrom<&'_ IOValue> for Predicate

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(value: &_Any) -> Result<Self, ParseError>

Performs the conversion.
