Struct rafx_base::resource_ref_map::ResourceRefMap

pub struct ResourceRefMap<'a> { /* fields omitted */ }

Like ResourceMap, but the insertions are temporary. This is an alternative to making a large amount of code generic just to pass down an arbitrary

Implementations

impl<'a> ResourceRefMap<'a>

pub fn new() -> Self

pub fn insert<R>(&mut self, r: &'a mut R) where
    R: Resource, 

Add a type/resource instance to the map

pub fn remove<R>(&mut self) -> Option<&'a mut R> where
    R: Resource, 

Remove a type/resource instance from the map

pub fn fetch<R: Resource>(&self) -> ResourceRefBorrow<'_, R>

Read-only fetch of a resource. Trying to get a resource that is not in the map is fatal. Use try_fetch if unsure whether the resource exists. Requesting read access to a resource that has any concurrently active writer is fatal.

pub fn try_fetch<R: Resource>(&self) -> Option<ResourceRefBorrow<'_, R>>

Read-only fetch of a resource. Requesting read access to a resource that has a concurrently active writer is fatal. Returns None if the type is not registered.

pub fn fetch_mut<R: Resource>(&self) -> ResourceRefBorrowMut<'_, R>

Read/Write fetch of a resource. Trying to get a resource that is not in the map is fatal. Use try_fetch if unsure whether the resource exists. Requesting write access to a resource with any concurrently active read/write is fatal

pub fn try_fetch_mut<R: Resource>(&self) -> Option<ResourceRefBorrowMut<'_, R>>

Read/Write fetch of a resource. Requesting write access to a resource with any concurrently active read/write is fatal. Returns None if the type is not registered.

pub fn has_value<R>(&self) -> bool where
    R: Resource, 

Returns true if the resource is registered.

Trait Implementations

impl<'a> Default for ResourceRefMap<'a>

fn default() -> ResourceRefMap<'a>

Returns the “default value” for a type.
