Trait for types that support path-based access

Required Associated Types

type Value

Associated value type accessed by path

fn get_path<'a>(&'a self, path: &str) -> Option<&'a Self::Value>

Get a reference to the value at path

fn set_path(&mut self, path: &str, value: Self::Value) -> bool

Set the value at path, returning true if set

Provided Methods

fn has_path(&self, path: &str) -> bool

True if a value exists at path
