The type returned in the event of a conversion error.

fn try_from(reference: Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl<'_r> TryFrom<&'_r Reference> for Storage

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(reference: &Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for Storage

Performs the conversion.

impl<'_r> TryFrom<&'_r Value> for Storage

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl InstanceOf for Storage

fn instance_of(reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.

impl ReferenceType for Storage

unsafe fn from_reference_unchecked(reference: Reference) -> Self

Converts a given reference into a concrete reference-like wrapper. Doesn't do any type checking; highly unsafe to use!

impl AsRef<Reference> for Storage

fn as_ref(&self) -> &Reference

Performs the conversion.

impl From<Storage> for Reference

fn from(value: Storage) -> Self

Performs the conversion.

impl Clone for Storage

fn clone(&self) -> Storage

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Eq for Storage

impl PartialEq<Storage> for Storage

fn eq(&self, other: &Storage) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Storage) -> bool

This method tests for !=.

impl Debug for Storage

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
