Enum FunctionReturn 

pub enum FunctionReturn {
    Trigger,
    Void,
    Type(ColumnTypeName),
    Other(String),
}

Variants

Trigger

RETURNS TRIGGER — the row-level trigger function shape. v7.12.4 ships exactly this for execution.

Void

RETURNS VOID. Parses; executor rejects in v7.12.4 unless the function is unused (since v7.12.4 doesn’t ship scalar function invocation).

Type(ColumnTypeName)

RETURNS <type> for any concrete data type. Reserved for v7.12.5+’s scalar UDF surface.

Other(String)

RETURNS <ident> for types SPG doesn’t know — extension types, RETURNS SETOF rows, RETURNS TABLE(…), etc.

Trait Implementations

impl Clone for FunctionReturn

fn clone(&self) -> FunctionReturn

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FunctionReturn

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FunctionReturn

fn eq(&self, other: &FunctionReturn) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
