Struct ArgSpan

pub struct ArgSpan {
    pub expr: Option<Expr>,
    pub sep: ArgSep,
    pub sep_pos: LineCol,
}

Single argument to a builtin call statement.

Fields

expr: Option<Expr>

Expression to compute the argument’s value. This expression is optional to support calls of the form PRINT a, , b where some arguments are empty.

sep: ArgSep

Separator between this argument and the next. The last instance of this type in a call always carries a value of ArgSep::End.

sep_pos: LineCol

Position of the sep.

Trait Implementations

impl Clone for ArgSpan

fn clone(&self) -> ArgSpan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArgSpan

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

Formats the value using the given formatter.

impl PartialEq for ArgSpan

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