Trait FromRef 

pub trait FromRef<InputTy> {
    // Required method
    fn from_ref(input: &InputTy) -> Self;
}

Available on crate features clients or servers only.

Used to do reference-to-value conversions thus not consuming the input value.

This is mainly used with state’s to extract “substates” from a reference to main application state.

Required Methods

fn from_ref(input: &InputTy) -> Self

Converts to this type from a reference to the input type.

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.
