Trait Implementations

impl Clone for AttributeValue

fn clone(&self) -> AttributeValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeValue

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

Formats the value using the given formatter.

impl Display for AttributeValue

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

Formats the value using the given formatter.

impl Hash for AttributeValue

The Hash and PartialEq implementations are only for internal use, for mapped providers.

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AttributeValue

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&Value> for AttributeValue

Try to create an AttributeValue from JSON.

type Error = JsonConversionError

The type returned in the event of a conversion error.

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

Performs the conversion.
