Struct FunctionCall

pub struct FunctionCall { /* private fields */ }

Function call.

Implementations

impl FunctionCall

pub fn arg<T>(self, arg: T) -> Self

where T: Into<SimpleExpr>,

Append an argument to the function call

pub fn args<I>(self, args: I) -> Self

where I: IntoIterator<Item = SimpleExpr>,

Replace the arguments of the function call

pub fn get_func(&self) -> &Function

pub fn get_args(&self) -> &[SimpleExpr]

pub fn get_mods(&self) -> &[FuncArgMod]

Trait Implementations

impl Clone for FunctionCall

fn clone(&self) -> FunctionCall

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionCall

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

Formats the value using the given formatter.

impl From<FunctionCall> for SimpleExpr

fn from(func: FunctionCall) -> Self

Converts to this type from the input type.

impl PartialEq for FunctionCall

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

impl PgExpr for FunctionCall

Available on crate feature backend-postgres only.

fn concatenate<T>(self, right: T) -> SimpleExpr

where T: Into<SimpleExpr>,

Express an postgres concatenate (||) expression.
