Trait treediff::Value

pub trait Value: PartialEq<Self> {
    type Key;
    type Item;

    // Required method
    fn items<'a>(
        &'a self
    ) -> Option<Box<dyn Iterator<Item = (Self::Key, &'a Self::Item)> + 'a>>;
}

Represents a scalar value or an associative array.

Required Associated Types

type Key

The Key type used to find Values in a mapping.

type Item

The Value type itself.

Required Methods

fn items<'a>( &'a self ) -> Option<Box<dyn Iterator<Item = (Self::Key, &'a Self::Item)> + 'a>>

Returns None if this is a scalar value, and an iterator yielding (Key, Value) pairs otherwise. It is entirely possible for it to yield no values though.

Object Safety

This trait is not object safe.

Implementations on Foreign Types
