pub struct DependencyQueue<K: Eq + Hash, V> { /* private fields */ }

Implementations

source

impl<K: Hash + Eq + Clone, V> DependencyQueue<K, V>

source

pub fn new() -> DependencyQueue<K, V>

Creates a new dependency queue with 0 packages.

source

pub fn queue(
    &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.

source

pub fn queue_finished(&mut self)

All nodes have been added, calculate some internal metadata and prepare for dequeue.

source

pub fn dequeue(&mut self) -> Option<(Freshness, K, V)>

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.

source

pub fn is_empty(&self) -> bool

Returns whether there are remaining packages to be built.

source

pub fn len(&self) -> usize

Returns the number of remaining packages to be built.

source

pub fn finish(&mut self, key: &K, fresh: Freshness)

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.
