Struct Reachability 

pub struct Reachability { /* private fields */ }

An exact object-ID set, sorted by identity, retaining the object-store snapshot used to find it.

Packed handles stay pinned through Self::objects. Loose objects remain live filesystem reads; this result does not prevent another writer from removing them. It is suitable for selecting a fetch response after the caller has resolved and authorized the want/have tips.

Implementations

impl Reachability

pub fn ids(&self) -> impl ExactSizeIterator<Item = ObjectId> + '_

Object identities in ascending order.

pub fn len(&self) -> usize

Number of objects in the difference.

pub fn is_empty(&self) -> bool

Whether the difference contains no objects.

pub fn count(&self, kind: ObjectKind) -> usize

Number of result objects of kind.

pub fn contains(&self, id: ObjectId) -> bool

Whether id belongs to this difference.

pub fn objects(&self) -> &Objects

The snapshot used by the query, for reading or packing the selected objects.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for Reachability

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