Struct FunctionOptions 

pub struct FunctionOptions { /* private fields */ }

Name, arity, and SQLite properties for a function registration.

Options default to UTF-8 and do not claim that a callback is deterministic, innocuous, or direct-only. These properties must reflect the callback’s actual behavior, so authors opt into them explicitly.

Implementations

impl FunctionOptions

pub fn new(name: impl Into<String>, arity: Arity) -> Self

Create schema-accessible UTF-8 function options.

pub fn deterministic(self) -> Self

Declare that equal inputs always produce equal outputs.

pub fn innocuous(self) -> Self

Declare that the function has no harmful side effects or data leaks.

pub fn direct_only(self) -> Self

Restrict the function to top-level SQL.

pub fn with_flags(self, flags: FunctionFlags) -> Self

Add advanced rusqlite function flags.

pub fn name(&self) -> &str

SQL function name.

pub const fn arity(&self) -> Arity

Declared SQL arity.

pub const fn flags(&self) -> FunctionFlags

Effective SQLite function flags.
