pub struct TempTag { /* private fields */ }

A hash and format pair that is protected from garbage collection.

If format is raw, this will protect just the blob If format is collection, this will protect the collection and all blobs in it

Implementations

impl TempTag

pub fn new(inner: HashAndFormat, on_drop: Option<Weak<dyn TagDrop>>) -> Self

Create a new temp tag for the given hash and format

This should only be used by store implementations.

The caller is responsible for increasing the refcount on creation and to make sure that temp tags that are created between a mark phase and a sweep phase are protected.

pub fn inner(&self) -> &HashAndFormat

The hash of the pinned item

pub fn hash(&self) -> &Hash

The hash of the pinned item

pub fn format(&self) -> BlobFormat

The format of the pinned item

pub fn hash_and_format(&self) -> HashAndFormat

The hash and format of the pinned item

pub fn leak(self)

Keep the item alive until the end of the process
