Struct CallArg 

pub struct CallArg {
    pub name: Option<String>,
    pub value: Expr,
}

Call argument (positional or named)

Fields

name: Option<String>

None = positional argument, Some = named argument (e.g., freq: 440)

value: Expr

Argument value

Implementations

impl CallArg

pub fn positional(value: Expr) -> Self

Create a positional argument.

pub fn named(name: impl Into<String>, value: Expr) -> Self

Create a named argument.

Trait Implementations

impl Clone for CallArg

fn clone(&self) -> CallArg

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CallArg

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

Formats the value using the given formatter.

impl PartialEq for CallArg

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