Trait ValueObjectAccessTryAsArray

pub trait ValueObjectAccessTryAsArray {
    type Key: ?Sized;
    type Array: Array;

    // Required method
    fn try_get_array<Q>(
        &self,
        k: &Q,
    ) -> Result<Option<&Self::Array>, TryTypeError>
       where Self::Key: Borrow<Q>,
             Q: ?Sized + Hash + Eq + Ord;
}

try_get_array access to object values in an object

Required Associated Types

type Key: ?Sized

The type for Objects

type Array: Array

The array structure

Required Methods

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

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

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

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.

Implementors

impl<T> ValueObjectAccessTryAsArray for T

where T: ValueObjectTryAccess + TypedValue, T::Target: ValueTryAsArray,

type Key = <T as ValueObjectTryAccess>::Key

type Array = <<T as ValueObjectTryAccess>::Target as ValueTryAsArray>::Array
