Trait DynamicHasField 

pub trait DynamicHasField {
    type Inner;

    // Required method
    fn resolve_path<P: OwnedPathType>(p: P, name: &str) -> P;
}

Available on crate feature resolve-path only.

A trait to declare that a type has fields with dynamic names, such as DirChildren, DirDescendants, etc.

This is used to resolve paths with resolve_path, particularly with the "name" and ${expr} syntaxes.

Required Associated Types

type Inner

The type of the field.

Required Methods

fn resolve_path<P: OwnedPathType>(p: P, name: &str) -> P

How to resolve the path for the field, from the path of Self, given the name passed into the resolve_path! macro.

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.
