Struct ValueDict 

pub struct ValueDict {
    pub map: BTreeMap<SmolStr, Value>,
    pub brand: Option<String>,
    pub variant_of: Option<String>,
}

Fields

map: BTreeMap<SmolStr, Value>

P2-17: dict keys land in a SmolStr so ≤ 22-byte field names (the overwhelming majority — see corpus telemetry) ride the inline slot and skip the per-key String allocation. SmolStr implements Borrow<str> so existing .get(&str) / .contains_key(&str) callsites keep working unchanged.

brand: Option<String>

variant_of: Option<String>

Name of the parent sum-type Enum when this dict is a tagged-enum variant. Some("Notification") distinguishes a Notification.Email payload from a plain #schema Email { ... } value (both have brand = Some("Email")); the JSON serializer uses it to wrap the payload as { Email: { ... } } only for the variant case.

Implementations

impl ValueDict

pub fn new<K, I>(map: I) -> Self

where K: Into<SmolStr>, I: IntoIterator<Item = (K, Value)>,

Build a ValueDict from any iterable of key/value pairs. Accepts both SmolStr (zero-cost) and String (consumed and SSO’d via SmolStr::from) keys; see Value::dict for the wider constructor.

pub fn with_brand<K, I>(map: I, brand: Option<String>) -> Self

where K: Into<SmolStr>, I: IntoIterator<Item = (K, Value)>,

Build a branded ValueDict. See ValueDict::new for the key-type contract.

Trait Implementations

impl Clone for ValueDict

fn clone(&self) -> ValueDict

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValueDict

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ValueDict

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ValueDict

fn eq(&self, other: &Self) -> 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 ValueDict

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
