Enum sql::func::TypeCategory

pub enum TypeCategory {
    Array,
    Bool,
    DateTime,
    List,
    Numeric,
    Pseudo,
    String,
    Timespan,
    UserDefined,
}

Mirrored from PostgreSQL’s typcategory.

Note that Materialize also uses a number of pseudotypes when planning, but we have yet to need to integrate them with TypeCategory.

Implementations

impl TypeCategory

fn from_type(typ: &ScalarType) -> Self

 'numeric', 'text', 'time', 'timestamp', 'timestamptz'
)
GROUP BY typcategory
ORDER BY typcategory;

fn from_param(param: &ParamType) -> Self

fn preferred_type(&self) -> Option<ScalarType>

Extracted from PostgreSQL 9.6.

SELECT typcategory, typname, typispreferred
FROM pg_catalog.pg_type
WHERE typispreferred = true
ORDER BY typcategory;
