Trait Fill 

pub trait Fill {
    // Required method
    fn fill(&self, slot: Slot<'_, '_>) -> Result<(), Error>;
}

A type that requires extra work to convert into a ValueBag.

This trait is an advanced initialization API. It’s intended for erased values coming from other logging frameworks that may need to perform extra work to determine the concrete type to use.

Required Methods

fn fill(&self, slot: Slot<'_, '_>) -> Result<(), Error>

Fill a value.

Dyn Compatibility

In older versions of Rust, dyn compatibility was called "object safety".
