Trait Macro

pub trait Macro {
    type Error: Into<ReportMessage>;
    type Node: TryFrom<AnyNode>;

    // Provided method
    fn transform(
        &mut self,
        guard: VisitGuard<'_, '_, Self::Node>,
        context: &mut impl Context,
    ) -> Execution<Self::Error, ChangeSet> { ... }
}

Required Associated Types

type Error: Into<ReportMessage>

type Node: TryFrom<AnyNode>

Provided Methods

fn transform( &mut self, guard: VisitGuard<'_, '_, Self::Node>, context: &mut impl Context, ) -> Execution<Self::Error, ChangeSet>

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.
