Enum launchdarkly_server_sdk::AttributeValue

pub enum AttributeValue {
    String(String),
    Array(Vec<AttributeValue>),
    Number(f64),
    Bool(bool),
    Object(HashMap<String, AttributeValue>),
    Null,
}

An attribute value represents possible values that can be stored in a crate::Context.

Variants

String(String)

Stores a string value.

Array(Vec<AttributeValue>)

Stores an array of attribute values.

Number(f64)

Stores a number.

Bool(bool)

Stores a boolean.

Object(HashMap<String, AttributeValue>)

Stores a map of attribute values.

Null

Stores a null value.

Implementations

impl AttributeValue

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

Returns None unless self is a String. It will not convert.

pub fn to_f64(&self) -> Option<f64>

Returns the wrapped value as a float for numeric types, and None otherwise.

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

Returns None unless self is a bool. It will not convert.

pub fn to_datetime(&self) -> Option<DateTime<Utc>>

Attempt to convert any of the following into a chrono::DateTime in UTC:

• RFC3339/ISO8601 timestamp (example: “2016-04-16T17:09:12.759-07:00”)
• Unix epoch milliseconds as number It will return None if the conversion fails or if no conversion is possible.

pub fn as_semver(&self) -> Option<Version>

Attempt to parse a string attribute into a semver version.

It will return None if it cannot parse it, or for non-string attributes.

pub fn find<P>(&self, p: P) -> Option<&AttributeValue>

where P: Fn(&AttributeValue) -> bool,

Find the AttributeValue based off the provided predicate p.

Trait Implementations

impl Clone for AttributeValue

fn clone(&self) -> AttributeValue

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AttributeValue

fn deserialize<__D>( __deserializer: __D ) -> Result<AttributeValue, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&Value> for AttributeValue

fn from(v: &Value) -> AttributeValue

Converts to this type from the input type.

impl From<&str> for AttributeValue

fn from(s: &str) -> AttributeValue

Converts to this type from the input type.

impl<S, T> From<HashMap<S, T>> for AttributeValue

where String: From<S>, AttributeValue: From<T>,

fn from(hashmap: HashMap<S, T>) -> AttributeValue

Converts to this type from the input type.

impl From<String> for AttributeValue

fn from(s: String) -> AttributeValue

Converts to this type from the input type.

impl<T> From<Vec<T>> for AttributeValue

where AttributeValue: From<T>,

fn from(v: Vec<T>) -> AttributeValue

Converts to this type from the input type.

impl From<bool> for AttributeValue

fn from(b: bool) -> AttributeValue

Converts to this type from the input type.

impl From<f64> for AttributeValue

fn from(f: f64) -> AttributeValue

Converts to this type from the input type.

impl From<i64> for AttributeValue

fn from(i: i64) -> AttributeValue

Converts to this type from the input type.

impl<S, T> FromIterator<(S, T)> for AttributeValue

where String: From<S>, AttributeValue: From<T>,

fn from_iter<I>(iter: I) -> AttributeValue

where I: IntoIterator<Item = (S, T)>,

Creates a value from an iterator.

impl<T> FromIterator<T> for AttributeValue

where AttributeValue: From<T>,

fn from_iter<I>(iter: I) -> AttributeValue

where I: IntoIterator<Item = T>,

Creates a value from an iterator.

impl PartialEq for AttributeValue

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

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

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

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

impl Serialize for AttributeValue

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
