[][src]Enum proc_macro2::Delimiter

pub enum Delimiter {
    Parenthesis,
    Brace,
    Bracket,
    None,
}

Describes how a sequence of token trees is delimited.

Variants

Parenthesis

( ... )

Brace

{ ... }

Bracket

[ ... ]

None

Ø ... Ø

An implicit delimiter, that may, for example, appear around tokens coming from a "macro variable" $var. It is important to preserve operator priorities in cases like $var * 3 where $var is 1 + 2. Implicit delimiters may not survive roundtrip of a token stream through a string.
