Struct Pet 

pub struct Pet<T, P>(/* private fields */);

A value that is accepted by a given predicate.

Implementations

impl<T, P: Pred<T>> Pet<T, P>

pub fn new(t: T) -> Option<Self>

Attempts to create a new Pet<T, P> from a value t.

If P accepts t, then the result is a Some(..) containing the value t. Otherwise, None is returned.

pub unsafe fn new_unchecked(t: T) -> Self

Creates a new Pet<T, P> from a value t without checking if P accepts t.

pub fn value(self) -> T

Retrieves the value contained in this Pet<T, P>.

Trait Implementations

impl<T, P> AsRef<T> for Pet<T, P>

fn as_ref(&self) -> &T

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

impl<T, P> Borrow<T> for Pet<T, P>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<T: Clone, P: Clone> Clone for Pet<T, P>

Formats the value using the given formatter.

impl<'de, T, P: Pred<T>> Deserialize<'de> for Pet<T, P>

where T: Deserialize<'de>,

Available on crate feature serde only.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T, P> Display for Pet<T, P>

where T: Display,

Formats the value using the given formatter.

impl<T, P> Hash for Pet<T, P>

where T: Hash,

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

where H: Hasher,

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<T, P> Ord for Pet<T, P>

where T: Ord,

fn cmp(&self, o: &Self) -> 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<T, P, Q> PartialEq<Pet<T, Q>> for Pet<T, P>

where T: PartialEq,

fn eq(&self, o: &Pet<T, Q>) -> bool

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

fn ne(&self, o: &Pet<T, Q>) -> bool

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

fn lt(&self, o: &Pet<T, Q>) -> bool

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

fn le(&self, o: &Pet<T, Q>) -> bool

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

fn gt(&self, o: &Pet<T, Q>) -> bool

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

fn ge(&self, o: &Pet<T, Q>) -> bool

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