Struct Function

pub struct Function {
    pub deterministic: bool,
    pub direct_only: bool,
    /* private fields */
}

Available on crate feature sqlite only.

Fields

deterministic: bool

the function always returns the same result given the same inputs

direct_only: bool

the function may only be invoked from top-level SQL, and cannot be used in VIEWs or TRIGGERs nor in schema structures such as CHECK constraints, DEFAULT clauses, expression indexes, partial indexes, or generated columns.
