Struct rhai::plugin::TypeId 1.0.0[−][src]
pub struct TypeId { /* fields omitted */ }
Expand description
A TypeId
represents a globally unique identifier for a type.
Each TypeId
is an opaque object which does not allow inspection of what’s
inside but does allow basic operations such as cloning, comparison,
printing, and showing.
A TypeId
is currently only available for types which ascribe to 'static
,
but this limitation may be removed in the future.
While TypeId
implements Hash
, PartialOrd
, and Ord
, it is worth
noting that the hashes and ordering will vary between Rust releases. Beware
of relying on them inside of your code!
Implementations
impl TypeId
[src]
impl TypeId
[src]pub const fn of<T>() -> TypeId where
T: 'static + ?Sized,
[src]
pub const fn of<T>() -> TypeId where
T: 'static + ?Sized,
[src]Returns the TypeId
of the type this generic function has been
instantiated with.
Examples
use std::any::{Any, TypeId}; fn is_string<T: ?Sized + Any>(_s: &T) -> bool { TypeId::of::<String>() == TypeId::of::<T>() } assert_eq!(is_string(&0), false); assert_eq!(is_string(&"cookie monster".to_string()), true);
