Trait DebugStructExt

pub trait DebugStructExt<'a, 'b> {
    // Required method
    fn maybe_field<T>(
        &mut self,
        name: &str,
        value: &Option<T>,
    ) -> &mut DebugStruct<'a, 'b>
       where T: Debug;
}

Required Methods

fn maybe_field<T>( &mut self, name: &str, value: &Option<T>, ) -> &mut DebugStruct<'a, 'b>

where T: Debug,

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.
