Struct TypeKey 

pub struct TypeKey { /* private fields */ }

A key for a type-erased value.

Implementations

impl TypeKey

pub fn new<T>() -> TypeKey

where T: Any + Send + Sync,

Create a new TypeKey.

pub const fn name(&self) -> &'static str

Returns the name of the type, if compiled with debug_assertions, otherwise "unknown".

Trait Implementations

impl Clone for TypeKey

fn clone(&self) -> TypeKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeKey

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

Formats the value using the given formatter.

impl Display for TypeKey

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

Formats the value using the given formatter.

impl Hash for TypeKey

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 PartialEq for TypeKey

fn eq(&self, other: &TypeKey) -> 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.
