struct ArmWrapper<'a> {
    arm: &'a Arm,
    is_last: bool,
    beginning_vert: Option<BytePos>,
}
Expand description

A simple wrapper type against ast::Arm. Used inside write_list().

Fields§

§arm: &'a Arm§is_last: bool

true if the arm is the last one in match expression. Used to decide on whether we should add trailing comma to the match arm when config.trailing_comma() == Never.

§beginning_vert: Option<BytePos>

Holds a byte position of | at the beginning of the arm pattern, if available.
