Struct FunctionArg 

pub struct FunctionArg {
    pub mode: FunctionArgMode,
    pub name: Option<String>,
    pub ty: FunctionArgType,
}

v7.12.4 — one positional argument to a CREATE FUNCTION.

Fields

mode: FunctionArgMode

IN / OUT / INOUT mode. v7.12.4 only accepts IN (the default); OUT / INOUT parse but the executor refuses them.

name: Option<String>

Optional arg name. Trigger functions traditionally don’t name their args (they read NEW/OLD instead), so None is the common case.

ty: FunctionArgType

Declared type, normalised to the SPG DataType mapping where one exists. Unknown / extension types parse as a raw string under FunctionArgType::Raw.

Trait Implementations

impl Clone for FunctionArg

fn clone(&self) -> FunctionArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionArg

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

Formats the value using the given formatter.

impl PartialEq for FunctionArg

fn eq(&self, other: &FunctionArg) -> 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.
