[−][src]Struct cargo::util::DependencyQueue
Methods
impl<K: Hash + Eq + Clone, V> DependencyQueue<K, V>[src]
pub fn new() -> DependencyQueue<K, V>[src]
Creates a new dependency queue with 0 packages.
pub fn queue(
&mut self,
fresh: Freshness,
key: &K,
value: V,
dependencies: &[K]
) -> &mut V[src]
&mut self,
fresh: Freshness,
key: &K,
value: V,
dependencies: &[K]
) -> &mut V
Adds a new package to this dependency queue.
It is assumed that any dependencies of this package will eventually also be added to the dependency queue.
pub fn queue_finished(&mut self)[src]
All nodes have been added, calculate some internal metadata and prepare
for dequeue.
pub fn dequeue(&mut self) -> Option<(Freshness, K, V)>[src]
Dequeues a package that is ready to be built.
A package is ready to be built when it has 0 un-built dependencies. If
None is returned then no packages are ready to be built.
pub fn is_empty(&self) -> bool[src]
Returns whether there are remaining packages to be built.
pub fn len(&self) -> usize[src]
Returns the number of remaining packages to be built.
pub fn finish(&mut self, key: &K, fresh: Freshness)[src]
Indicate that a package has been built.
This function will update the dependency queue with this information,
possibly allowing the next invocation of dequeue to return a package.
