Enum 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 context 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§

Source§

impl FlagValue

Source

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

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

Source

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

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

Source

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

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

Source

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

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

Source

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

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