Struct runestick::Mut [−][src]
A strong mutable reference to the given type.
Implementations
impl<T: ?Sized> Mut<T>[src]
pub fn map<U: ?Sized, F>(this: Self, f: F) -> Mut<U>ⓘ where
F: FnOnce(&mut T) -> &mut U, [src]
F: FnOnce(&mut T) -> &mut U,
Map the interior reference of an owned mutable value.
Examples
use runestick::{Mut, Shared}; let vec = Shared::<Vec<u32>>::new(vec![1, 2, 3, 4]); let vec = vec.into_mut()?; let value: Mut<[u32]> = Mut::map(vec, |vec| &mut vec[0..2]); assert_eq!(&*value, &mut [1u32, 2u32][..]);
pub fn try_map<U: ?Sized, F>(this: Self, f: F) -> Option<Mut<U>> where
F: FnOnce(&mut T) -> Option<&mut U>, [src]
F: FnOnce(&mut T) -> Option<&mut U>,
Try to map the mutable reference to a projection.
Examples
use runestick::{Mut, Shared}; let vec = Shared::<Vec<u32>>::new(vec![1, 2, 3, 4]); let vec = vec.into_mut()?; let mut value: Option<Mut<[u32]>> = Mut::try_map(vec, |vec| vec.get_mut(0..2)); assert_eq!(value.as_deref_mut(), Some(&mut [1u32, 2u32][..]));
pub fn into_raw(this: Self) -> (*mut T, RawMut)[src]
Convert into a raw pointer and associated raw access guard.
Safety
The returned pointer must not outlive the associated guard, since this prevents other uses of the underlying data which is incompatible with the current.
