Struct assets_manager::AssetReadGuard

pub struct AssetReadGuard<'a, T: ?Sized> { /* private fields */ }

RAII guard used to keep a read lock on an asset and release it when dropped.

This type is a smart pointer to type T.

It can be obtained by calling Handle::read.

Implementations

impl<'a, T: ?Sized> AssetReadGuard<'a, T>

pub fn map<U: ?Sized, F>(this: Self, f: F) -> AssetReadGuard<'a, U>

where F: FnOnce(&T) -> &U,

Make a new AssetReadGuard for a component of the locked data.

pub fn try_map<U: ?Sized, F>( this: Self, f: F ) -> Result<AssetReadGuard<'a, U>, Self>

where F: FnOnce(&T) -> Option<&U>,

Attempts to make a new AssetReadGuard for a component of the locked data.

Returns the original guard if the closure returns None.

impl<'a> AssetReadGuard<'a, dyn Any>

pub fn downcast<T: Any>(self) -> Result<AssetReadGuard<'a, T>, Self>

Attempt to downcast the guard to a concrete type.

impl<'a> AssetReadGuard<'a, dyn Any + Send>

pub fn downcast<T: Any>(self) -> Result<AssetReadGuard<'a, T>, Self>

Attempt to downcast the guard to a concrete type.

impl<'a> AssetReadGuard<'a, dyn Any + Send + Sync>

pub fn downcast<T: Any>(self) -> Result<AssetReadGuard<'a, T>, Self>

Attempt to downcast the guard to a concrete type.
