Trait FoldableExpression

pub trait FoldableExpression<'i>: Sized {
    // Required method
    fn fold<F>(self, folder: &mut F, span: Span<'i>) -> Result<Self, F::Error>
       where F: ExpressionFolder<'i, Self> + ?Sized;
}

Expression item that can be transformed recursively by using folder: F.

Required Methods

fn fold<F>(self, folder: &mut F, span: Span<'i>) -> Result<Self, F::Error>

where F: ExpressionFolder<'i, Self> + ?Sized,

Transforms self by applying the folder to inner items.

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.
