Struct FunctionAttrs 

pub struct FunctionAttrs {
    pub volatility: FunctionVolatility,
    pub strict: bool,
    pub security_definer: bool,
    pub leakproof: bool,
    pub parallel: FunctionParallel,
    pub cost: Option<f64>,
    pub rows: Option<f64>,
}

v7.39 (round 322, V46) — the attribute clauses CREATE FUNCTION accepts on either side of its body. Defaults are PG’s: VOLATILE, called on null input, SECURITY INVOKER, not leakproof, PARALLEL UNSAFE, and the language’s default cost / rows.

Fields

volatility: FunctionVolatility

strict: bool

STRICT / RETURNS NULL ON NULL INPUT: a call with any NULL argument returns NULL without running the body.

security_definer: bool

leakproof: bool

parallel: FunctionParallel

cost: Option<f64>

COST n — None leaves PG’s per-language default.

rows: Option<f64>

ROWS n — set-returning functions only; None = default.

Implementations

impl FunctionAttrs

pub fn render_words(&self) -> Vec<String>

The attribute words pg_get_functiondef puts on their own line, in PG’s order (measured on 18.4: volatility, PARALLEL, STRICT, SECURITY DEFINER, LEAKPROOF, COST, ROWS). Empty when everything is at its default — PG then emits no such line at all.
