Enum FlagValue 

pub enum FlagValue {
    Bool(bool),
    String(String),
    Int(i64),
    Json(String),
}

A single flag value. Four concrete shapes cover every flag provider the plan lists (OpenFeature, Unleash, LaunchDarkly, Statsig) without making any of them special.

Json carries a JSON-encoded string rather than a serde_json::Value so the whole enum round-trips through the WASM ABI as plain bytes. The caller parses the string in its own code if it needs structured access.

Variants

Bool(bool)

Boolean flag. Used for kill-switches, simple on/off rollouts.

String(String)

String flag. Used for A/B/C-style variants (“control”, “treatment”).

Int(i64)

Integer flag. Used for numeric thresholds (batch sizes, timeouts).

Json(String)

JSON-encoded structured flag. The string is always a valid JSON document; the backend guarantees this.

Implementations

impl FlagValue

pub fn as_bool(&self) -> bool

Convenience: true if this is a Bool(true). For every other variant, including Bool(false), returns false.

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

Convenience accessor for string variants. Returns None for every other shape — callers decide whether to coerce or treat as a miss.

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

Convenience accessor for integer variants.

Trait Implementations

impl Clone for FlagValue

fn clone(&self) -> FlagValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlagValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FlagValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FlagValue

fn eq(&self, other: &FlagValue) -> 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 Serialize for FlagValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
