Struct EnumVariant 

pub struct EnumVariant {
    pub name: String,
    pub tag: u8,
    pub fields: Vec<Field>,
    pub is_tuple: bool,
}

One variant in a canonical #enum description.

Fields

name: String

Variant name as declared in source.

tag: u8

Stable ABI tag. Tags are assigned in declaration order and must fit in one byte for the current variant-record layout.

fields: Vec<Field>

Payload fields. Empty means a unit variant.

is_tuple: bool

true when the payload came from a tuple variant, e.g. Rgb(Int, Int, Int). Field names are then synthetic decimal indices ("0", "1", …), and host JSON projection emits an array payload.

Implementations

impl EnumVariant

pub fn payload_schema(&self, enum_name: &str) -> Option<Schema>

Build the record schema used for this variant’s payload. Tuple variants deliberately use a normal record schema with numeric field names, because Value::variant_dict stores tuple payloads as a dict; JSON projection recognizes those numeric keys and emits an array.

Trait Implementations

impl Clone for EnumVariant

fn clone(&self) -> EnumVariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EnumVariant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EnumVariant

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EnumVariant

impl PartialEq for EnumVariant

fn eq(&self, other: &EnumVariant) -> 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 EnumVariant

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
