Struct Teardown 

pub struct Teardown<Cx: ?Sized> { /* private fields */ }

Releases a set of resources in reverse registration order — the inverse of how they were built, which is the only order that is safe when later resources borrow earlier ones.

One failure does not abandon the rest: every resource is released, and the first error is returned afterwards. A half-torn-down GPU is worse than a reported error.

Implementations

impl<Cx: ?Sized> Teardown<Cx>

pub fn new() -> Self

pub fn push(&mut self, resource: Box<dyn ModelResource<Cx>>)

Register a resource. Registration order is construction order.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn release_all(&mut self, cx: &Cx) -> Result<()>

Release everything, newest first. Returns the first failure, after having attempted them all.

Trait Implementations

impl<Cx: ?Sized> Default for Teardown<Cx>

fn default() -> Self

Returns the “default value” for a type.
