Enum launchdarkly_server_sdk::FlagValue

source · [−]

pub enum FlagValue {
    Bool(bool),
    Str(String),
    Number(f64),
    Json(Value),
}

Expand description

FlagValue represents any of the data types supported by JSON, all of which can be used for a LaunchDarkly feature flag variation or a custom user attribute.

Variants

`Bool(bool)`

Used when the value is a boolean.

`Str(String)`

Used when the value is a string.

`Number(f64)`

Used when the value is a number.

`Json(Value)`

Used when the value is an arbitrary JSON value.

Implementations

impl FlagValue

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

Attempts to convert the FlagValue into a boolean representation, returning None if the conversion is invalid.

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

Attempts to convert the FlagValue into a string representation, returning None if the conversion is invalid.

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

Attempts to convert the FlagValue into a float representation, returning None if the conversion is invalid.

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

Attempts to convert the FlagValue into a integer representation, returning None if the conversion is invalid.

pub fn as_json(&self) -> Option<Value>

Attempts to convert the FlagValue into an arbitrary JSON representation, returning None if the conversion is invalid.
