Struct Cursor

pub struct Cursor<'a, 'find> { /* private fields */ }

A way to constrain all tree-edits to a given subtree.

Implementations

impl Cursor<'_, '_>

pub fn upsert<I, C>( &mut self, rela_path: I, kind: EntryKind, id: ObjectId, ) -> Result<&mut Self, Error>

where I: IntoIterator<Item = C>, C: AsRef<BStr>,

Like Editor::upsert(), but with the constraint of only editing in this cursor’s tree.

pub fn remove<I, C>(&mut self, rela_path: I) -> Result<&mut Self, Error>

where I: IntoIterator<Item = C>, C: AsRef<BStr>,

Like Editor::remove(), but with the constraint of only editing in this cursor’s tree.

pub fn write<E>( &mut self, out: impl FnMut(&Tree) -> Result<ObjectId, E>, ) -> Result<ObjectId, E>

Like Editor::write(), but will write only the subtree of the cursor.
