Enum TraverseControl

Source

pub enum TraverseControl<S, U> {
    ContinueWithScope(S),
    Continue,
    SkipBranch,
    Return(U),
}

Expand description

Flow control for tree traverals.

Variants§

§

ContinueWithScope(S)

Normal control flow: continue recursing into the children.

Pass the state &S to all children.

§

Continue

Normal control flow: continue recursing into the children.

The state that was passed to the parent will be re-used for the children.

§

SkipBranch

Skip this branch of the tree.

§

Return(U)

Finish traversing immediately (and return a value).
