Expand description

A trait to extend Reference with functionality requiring a file::Store.

Required methods

A step towards obtaining forward or reverse iterators on reference logs.

For details, see Reference::log_exists().

For details, see Reference::peel_to_id_in_place().

For details, see Reference::peel_to_id_in_place(), with support for a known stable packed buffer.

Follow this symbolic reference one level and return the ref it refers to.

Returns None if this is not a symbolic reference, hence the leaf of the chain.

Follow this symbolic reference one level and return the ref it refers to, possibly providing access to packed references for lookup if it contains the referent.

Returns None if this is not a symbolic reference, hence the leaf of the chain.
