Trait OptSpanned

pub trait OptSpanned {
    // Required method
    fn opt_span(&self) -> Option<Span>;

    // Provided method
    fn opt_join_span(&self, other: &impl OptSpanned) -> Option<Span> { ... }
}

Compute an optional byte span of an ast fragment

Required Methods

fn opt_span(&self) -> Option<Span>

Compute an optional byte span of an ast fragment

Provided Methods

fn opt_join_span(&self, other: &impl OptSpanned) -> Option<Span>

Compute the minimal span containing both self and other if either is missing return the other

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.
