impl TypeId

1.0.0 (const: unstable) · source

pub fn of<T>() -> TypeIdwhere T: 'static + ?Sized,

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);

impl PartialEq<TypeId> for TypeId

source§

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

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