Struct SingletonRef 

pub struct SingletonRef {
    pub hash: Pound,
    pub access_group: Option<(Brace, LitInt)>,
    pub token_mut: Option<Mut>,
    pub ident: Ident,
}

A parsed singleton reference token with mutability and optional access group.

Syntax: #var, #mut var, #{N} var, #{N} mut var

Fields

hash: Pound

Hash # marking the start of the singleton.

access_group: Option<(Brace, LitInt)>

Optional access group for ordering (#{N} prefix). Stores the brace group and parsed integer.

token_mut: Option<Mut>

Whether this is a mutable reference (#mut var or #{N} mut var).

ident: Ident

The variable name being referenced.
