[−][src]Struct reffers::aref::ARefs
ARefs is a version of ARef that implements Send.
It works just like ARef, except that its owner must implement Send, and thus the struct implements Send as well.
Methods
impl<'a, U: ?Sized> ARefs<'a, U>
[src]
pub fn new<O>(owner: O) -> Self where
O: 'a + AReffic + Send + Deref<Target = U>,
[src]
O: 'a + AReffic + Send + Deref<Target = U>,
Creates a new ARefs from what the ARefs points to.
Example
use reffers::ARefs; let aref = ARefs::new(Box::new(43)); assert_eq!(*aref, 43);
pub fn map<V: ?Sized, F: FnOnce(&U) -> &V>(self, f: F) -> ARefs<'a, V>
[src]
Maps the ARefs' target to something reachable from the target.
Example
use reffers::ARefs; let aref: ARefs<[u8]> = vec![0u8, 5, 7].into(); assert_eq!(*aref.map(|s| &s[1]), 5);
pub fn try_map<E, V: ?Sized, F: FnOnce(&U) -> Result<&V, E>>(
self,
f: F
) -> Result<ARefs<'a, V>, E>
[src]
self,
f: F
) -> Result<ARefs<'a, V>, E>
Like map, but with Result passthrough.
Example
use reffers::ARefs; let aref = ARefs::<[u8]>::from(vec![0u8, 5, 7]); assert_eq!(aref.try_map(|s| s.get(9).ok_or(())), Err(()));
pub fn into_aref(self) -> ARef<'a, U>
[src]
Removes the type information that this struct is Send + Sync.
