Struct by_address::ByAddress

#[repr(transparent)]
pub struct ByAddress<T>(pub T)
where
    T: ?Sized + Deref;

Wrapper for pointer types that implements by-address comparison.

See the crate-level documentation for details.

Equality tests and hashes on fat pointers (&dyn Trait, &[T], &str, etc) include the attribute of the fat pointer.

However, note that comparing fat pointers to trait objects can be unreliable because of Rust issue #46139. In some cases, ByThinAddress may be more useful.

Implementations

impl<T> ByAddress<T>

where T: ?Sized + Deref,

pub fn from_ref(r: &T) -> &Self

Convert &T to &ByAddress<T>.

Trait Implementations

impl<T, U> AsMut<U> for ByAddress<T>

where T: ?Sized + Deref + AsMut<U>,

fn as_mut(&mut self) -> &mut U

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

impl<T, U> AsRef<U> for ByAddress<T>

where T: ?Sized + Deref + AsRef<U>,

fn as_ref(&self) -> &U

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

impl<T> Clone for ByAddress<T>

where T: ?Sized + Deref + Clone,

fn clone(&self) -> ByAddress<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ByAddress<T>

where T: ?Sized + Deref + Debug,

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

Formats the value using the given formatter.

impl<T> Default for ByAddress<T>

where T: ?Sized + Deref + Default,

fn default() -> ByAddress<T>

Returns the “default value” for a type.

impl<T> Deref for ByAddress<T>

where T: ?Sized + Deref,

type Target = T

The resulting type after dereferencing.

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

Dereferences the value.

impl<T> DerefMut for ByAddress<T>

where T: ?Sized + Deref,

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<T> Display for ByAddress<T>

where T: ?Sized + Deref + Display,

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

Formats the value using the given formatter.

impl<T> From<T> for ByAddress<T>

where T: Deref,

fn from(t: T) -> ByAddress<T>

Converts to this type from the input type.

impl<T> Hash for ByAddress<T>

where T: ?Sized + Deref,

Raw pointer hashing

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

Feeds this value into the given Hasher.

impl<T> Ord for ByAddress<T>

where T: ?Sized + Deref,

Raw pointer ordering

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

impl<T> PartialEq for ByAddress<T>

where T: ?Sized + Deref,

Raw pointer equality

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

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

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

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

impl<T> PartialOrd for ByAddress<T>

where T: ?Sized + Deref,

Raw pointer comparison

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

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<T> Copy for ByAddress<T>

where T: ?Sized + Deref + Copy,

impl<T> Eq for ByAddress<T>

where T: ?Sized + Deref,
