Struct pex::BracketPattern

pub struct BracketPattern {
    pub open: &'static str,
    pub close: &'static str,
    pub delimiter: &'static str,
    pub dangling: Option<bool>,
    pub one_tailing: bool,
}

A bracket pattern like [] or (1, )

Fields

open: &'static str

The open bracket pattern

close: &'static str

The close bracket pattern

delimiter: &'static str

The delimiter of the bracket elements

dangling: Option<bool>

Whether the last element can be dangling

one_tailing: bool

Need add delimiter if there is only one element
