TypeExpr

Enum TypeExpr 

Source
pub enum TypeExpr {
    Name(Spanned<String>),
    Parameterized {
        name: Spanned<String>,
        args: Vec<Spanned<TypeExpr>>,
    },
    Union(Vec<Spanned<TypeExpr>>),
    Optional(Box<Spanned<TypeExpr>>),
    Literal(Literal),
    Object(Vec<(Spanned<String>, Spanned<TypeExpr>)>),
    Partial(PartialNode),
}
Expand description

A syntactic type expression, kept independent of surrealdb_types::Kind.

Variants§

§

Name(Spanned<String>)

string, int, record, …

§

Parameterized

array<string>, record<user>, set<int, 5>, …

Fields

§name: Spanned<String>

The base type constructor (array, record, set, …).

§args: Vec<Spanned<TypeExpr>>

The type arguments inside <...>.

§

Union(Vec<Spanned<TypeExpr>>)

int | string

§

Optional(Box<Spanned<TypeExpr>>)

option<...> sugar and the grammar’s optional marker.

§

Literal(Literal)

A literal type: 'active', 42, true — usually inside unions.

§

Object(Vec<(Spanned<String>, Spanned<TypeExpr>)>)

An object type: { name: string, age: int } — each property maps a name to its own type expression.

§

Partial(PartialNode)

Other unmodeled type syntax: explicit, never dropped.
