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: booltrue 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.
