Struct FunctionArgList 

pub struct FunctionArgList {
    pub distinct: bool,
    pub args: Vec<FunctionArg>,
    pub variadic: bool,
    pub order_by: Vec<OrderByExpr>,
    pub ignore_nulls: bool,
}

A list of function arguments, including additional modifiers like DISTINCT or ORDER BY. This basically holds all the information between the ( and ) in a function call.

Fields

distinct: bool

Aggregate function calls may have a DISTINCT, e.g. count(DISTINCT x).

args: Vec<FunctionArg>

variadic: bool

Whether the last argument is variadic, e.g. foo(a, b, VARIADIC c).

order_by: Vec<OrderByExpr>

Aggregate function calls may have an ORDER BY, e.g. array_agg(x ORDER BY y).

ignore_nulls: bool

Window function calls may have an IGNORE NULLS, e.g. first_value(x IGNORE NULLS).

Implementations

impl FunctionArgList

pub fn empty() -> Self

pub fn args_only(args: Vec<FunctionArg>) -> Self

pub fn is_args_only(&self) -> bool

pub fn for_agg( distinct: bool, args: Vec<FunctionArg>, order_by: Vec<OrderByExpr>, ) -> Self

Trait Implementations

impl Clone for FunctionArgList

fn clone(&self) -> FunctionArgList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionArgList

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

Formats the value using the given formatter.

impl Display for FunctionArgList

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

Formats the value using the given formatter.

impl Eq for FunctionArgList

impl Hash for FunctionArgList

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FunctionArgList

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