Struct NegotiateContext

pub struct NegotiateContext<'a, 'b, 'c, Objects, Alternates, AlternatesOut, AlternatesErr, Find>
where
    Objects: Find + FindHeader + Exists,
    Alternates: FnOnce() -> Result<AlternatesOut, AlternatesErr>,
    AlternatesErr: Into<Box<dyn Error + Send + Sync + 'static>>,
    AlternatesOut: Iterator<Item = (Store, Find)>,

}

Available on crate feature fetch only.

For use in fetch.

Fields

objects: &'a Objects

Access to the object database. Note that the exists() calls must not trigger a refresh of the ODB packs as plenty of them might fail, i.e. find on object.

refs: &'a Store

Access to the git references database.

alternates: Alternates

A function that returns an iterator over (refs, objects) for each alternate repository, to assure all known objects are added also according to their tips.

negotiator: &'a mut dyn Negotiator

The implementation that performs the negotiation later, i.e. prepare wants and haves.

graph: &'a mut Graph<'b, 'c>

The commit-graph for use by the negotiator - we populate it with tips to initialize the graph traversal.
