Struct ProviderCache 

pub struct ProviderCache {
    pub pushed: PushedPairs,
    /* private fields */
}

What provider dogs have pushed: the values, and which (namespace, environment) pairs carry a push at all.

The two travel together because they are read together and must come from one moment: a values map from before a push read beside a pair set from after it would call a key permanently missing that the push had just supplied.

An empty push is why the pair set is not derivable from the values. A dog saying “I have nothing for staging” registers the pair and holds no keys, which is a different answer from a dog that has not pushed.

Debug does not leak a value: it prints two counts.

Fields

pushed: PushedPairs

Every (namespace, environment) pair a push has landed for.

Names, never values, which is why this half stays public: the shepherd’s boot log prints it as it stands.

Implementations

impl ProviderCache

pub fn new(values: NamespaceValues, pushed: PushedPairs) -> Self

A cache holding values, pushed as the pairs in pushed.

pub fn namespace(&self, name: &str) -> Option<&NamespaceTable>

One namespace’s values, or nothing when no push has carried that namespace.

Present and empty is a dog that pushed no keys. Whether that dog has spoken for a given environment is Self::pushed’s answer, not this one’s.

pub fn namespaces(&self) -> impl Iterator<Item = (&String, &NamespaceTable)>

Every namespace and its values, in name order.

pub fn namespace_count(&self) -> usize

How many namespaces a push has carried.

pub fn into_parts(self) -> (NamespaceValues, PushedPairs)

Both halves, moved out, for a caller that owns them afterwards.

Trait Implementations

impl Clone for ProviderCache

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProviderCache

Redacted (IR-41): values holds provider values in the clear.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProviderCache

fn default() -> Self

Returns the “default value” for a type.
