Trait ConfigField 

pub trait ConfigField {
    // Required methods
    fn visit<V>(&self, v: &mut V, key: &str, description: &'static str)
       where V: Visit;
    fn set(&mut self, key: &str, value: &str) -> Result<(), DataFusionError>;

    // Provided method
    fn reset(&mut self, key: &str) -> Result<(), DataFusionError> { ... }
}

A trait implemented by config_namespace and for field types that provides the ability to walk and mutate the configuration tree

Required Methods

fn visit<V>(&self, v: &mut V, key: &str, description: &'static str)

where V: Visit,

fn set(&mut self, key: &str, value: &str) -> Result<(), DataFusionError>

Provided Methods

fn reset(&mut self, key: &str) -> Result<(), DataFusionError>

Dyn Compatibility

This trait is not dyn compatible.

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