Expand description

MovePath is a canonicalized representation of a path that is moved or assigned to.

It follows a tree structure.

Given struct X { m: M, n: N } and x: X, moves like drop x.m; move out of the place x.m.

The MovePaths representing x.m and x.n are siblings (that is, one of them will link to the other via the next_sibling field, and the other will have no entry in its next_sibling field), and they both have the MovePath representing x as their parent.

Implementations§

source§

impl<'tcx> MovePath<'tcx>

source

pub fn parents<'a>( &self, move_paths: &'a IndexSlice<MovePathIndex, MovePath<'tcx>>, ) -> impl 'a + Iterator<Item = (MovePathIndex, &'a MovePath<'tcx>)>

Returns an iterator over the parents of self.

source

pub fn children<'a>( &self, move_paths: &'a IndexSlice<MovePathIndex, MovePath<'tcx>>, ) -> impl 'a + Iterator<Item = (MovePathIndex, &'a MovePath<'tcx>)>

Returns an iterator over the immediate children of self.

source

pub fn find_descendant( &self, move_paths: &IndexSlice<MovePathIndex, MovePath<'_>>, f: impl Fn(MovePathIndex) -> bool, ) -> Option<MovePathIndex>

Finds the closest descendant of self for which f returns true using a breadth-first search.

f will not be called on self.
