Enum TypedObjectFieldSource 

pub enum TypedObjectFieldSource {
    Literal(ExprId),
    Absent(ExprId),
    Spread {
        source_index: usize,
        field_name: String,
        source_ty: Type,
        fallback: Option<Box<TypedObjectFieldSource>>,
    },
}

Variants

Literal(ExprId)

Absent(ExprId)

Spread

source_index counts the literal’s Spread members; source_ty is the spread’s Type::Object so codegen can index by BTreeMap order.

Fields

source_index: usize

field_name: String

source_ty: Type

fallback: Option<Box<TypedObjectFieldSource>>

Set when the source’s field is optional and an earlier member wrote the same field: an absent field leaves that earlier value in place, as in JavaScript, where { a: 1, ...{} } keeps a: 1.
