try_as_* access to container values in an object

Required Associated Types

type Key: ?Sized

The type for Objects

type Target

The target for nested lookups

type Array: Array

The array structure

type Object: Object

The object structure

Required Methods

fn try_get_array<Q>(&self, k: &Q) -> Result<Option<&Self::Array>, TryTypeError>

where Self::Key: Borrow<Q> + Hash + Eq, Q: Hash + Eq + Ord + ?Sized,

Tries to get an element of an object as an array, returns an error if it isn’t a array

Errors

if the requested type doesn’t match the actual type or the value is not an object

fn try_get_object<Q>( &self, k: &Q, ) -> Result<Option<&Self::Object>, TryTypeError>

where Self::Key: Borrow<Q> + Hash + Eq, Q: Hash + Eq + Ord + ?Sized,

Tries to get an element of an object as an object, returns an error if it isn’t an object

Errors

if the requested type doesn’t match the actual type or the value is not an object

Object Safety

This trait is not object safe.
