Struct CallArg 

pub struct CallArg {
    pub mode: ArgMode,
    pub expr: Expr,
    pub span: Span,
}

An argument in a function call.

Fields

mode: ArgMode

The passing mode for this argument

expr: Expr

The argument expression

span: Span

Span covering the entire argument (including inout/borrow keyword if present)

Implementations

impl CallArg

pub fn is_inout(&self) -> bool

Returns true if this argument is passed as inout. This is a convenience method for backwards compatibility.

pub fn is_borrow(&self) -> bool

Returns true if this argument is passed as borrow.

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.
