Struct TempTag

pub struct TempTag { /* private fields */ }

An ephemeral, in-memory tag that protects content while the process is running.

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 leaking_empty(format: BlobFormat) -> Self

The empty temp tag. We don’t track the empty blob since we always have it.

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(&mut self)

Keep the item alive until the end of the process
