Struct Ref

pub struct Ref<'a, T: 'a> { /* private fields */ }

Implementations

impl<'a, T: 'a> Ref<'a, T>

pub fn new(borrow: Shared<'a>, value: &'a T) -> Self

pub fn map_into<K: 'a, F: FnMut(&'a T) -> K>(self, f: F) -> RefMap<'a, K>

pub fn map<K: 'a, F: FnMut(&T) -> &K>(&self, f: F) -> Ref<'a, K>

pub unsafe fn deconstruct(self) -> (Shared<'a>, &'a T)

Deconstructs this mapped borrow to its underlying borrow state and value.

Safety

Ensure that you still follow all safety guidelines of this mapped ref.

Trait Implementations

impl<'a, T: 'a> AsRef<T> for Ref<'a, T>

fn as_ref(&self) -> &T

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

impl<'a, T: 'a> Borrow<T> for Ref<'a, T>

fn borrow(&self) -> &T

Immutably borrows from an owned value.

impl<'a, T: 'a> Clone for Ref<'a, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug + 'a> Debug for Ref<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: 'a> Deref for Ref<'a, T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, T> Hash for Ref<'a, T>

where T: 'a + Hash,

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<'a, T> Ord for Ref<'a, T>

where T: 'a + Ord,

fn cmp(&self, other: &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<'a, T> PartialEq for Ref<'a, T>

where T: 'a + PartialEq,

fn eq(&self, other: &Self) -> 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<'a, T> PartialOrd for Ref<'a, T>

where T: 'a + PartialOrd,

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

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

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

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

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

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

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

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

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

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

impl<'a, T> Eq for Ref<'a, T>

where T: 'a + Eq,
