Struct ResourceLease 

Source 
pub struct ResourceLease<R: Send + 'static> { /* private fields */ }
Expand description

An exclusive lease on a resource.

Dereferences to the resource itself. Dropping the lease returns the resource to the registry still live, so a lease is a loan, never ownership. See ResourceRegistry for the full model.

Implementations§

Source§

impl<R: Send + 'static> ResourceLease<R>

Source

pub fn kind(&self) -> ResourceKind

Returns the kind of this resource.

Source

pub fn key(&self) -> &MetaString

Returns the key this resource is registered under, unique within its kind.

Source

pub fn release(self)

Returns the resource to the registry.

Equivalent to dropping the lease; useful where the return should be obvious at the call site.

Source

pub fn discard(self)

Drops the resource instead of returning it, so the next acquisition creates a fresh one.

Use this when the resource has hit an error it can’t recover from and handing it to the next acquirer would pass the problem along.
