Trait VisitFlowExt 

pub trait VisitFlowExt {
    const DESCEND: ControlFlow<VisitBreak, VisitAction> = _;
    const SKIP_CHILDREN: ControlFlow<VisitBreak, VisitAction> = _;
    const STOP: ControlFlow<VisitBreak, VisitAction> = _;
}

Named VisitFlow values.

VisitFlow is a type alias for ControlFlow, so the canonical values are exposed as associated consts via this extension trait rather than inherent consts. Bringing the trait into scope lets you write VisitFlow::DESCEND, VisitFlow::SKIP_CHILDREN, and VisitFlow::STOP.

Provided Associated Constants

const DESCEND: ControlFlow<VisitBreak, VisitAction> = _

Continue traversal and recurse into children.

const SKIP_CHILDREN: ControlFlow<VisitBreak, VisitAction> = _

Continue traversal but skip visiting children (exit_* still fires).

const STOP: ControlFlow<VisitBreak, VisitAction> = _

Stop traversal immediately.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
