Implementations

impl AttributeValue

pub fn string<S: Into<String>>(value: S) -> Self

Create a string attribute

pub fn integer(value: i64) -> Self

Create an integer attribute

pub fn float(value: f64) -> Self

Create a float attribute

pub fn boolean(value: bool) -> Self

Create a boolean attribute

pub fn json<T: Serialize>(value: &T) -> Result<Self>

Create a JSON attribute from any serializable type

pub fn as_string(&self) -> Option<&str>

Get the attribute as a string

pub fn as_integer(&self) -> Option<i64>

Get the attribute as an integer

pub fn as_float(&self) -> Option<f64>

Get the attribute as a float

pub fn as_boolean(&self) -> Option<bool>

Get the attribute as a boolean

pub fn as_json<T: DeserializeOwned>(&self) -> Result<T>

Get the attribute as a typed value from JSON

pub fn to_string_repr(&self) -> String

Convert any attribute value to a string representation

Trait Implementations

impl Clone for AttributeValue

fn clone(&self) -> AttributeValue

Returns a duplicate of the value.

const 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 Hash for AttributeValue

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: &AttributeValue) -> bool

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

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

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