Macro yarpl::repeat

macro_rules! repeat {
    ($visibility:vis $name:ident { $to_repeat:ident; { $lower:expr , } } ) => { ... };
    ($visibility:vis $name:ident { $to_repeat:ident; { , $upper:expr } } ) => { ... };
    ($visibility:vis $name:ident { $to_repeat:ident; { , } } ) => { ... };
    ($visibility:vis $name:ident { $to_repeat:ident; { $amount:expr } } ) => { ... };
    ($visibility:vis $name:ident { $to_repeat:ident; { $lower:expr , $upper:expr } } ) => { ... };
}

Using a modified, regular-expression-like syntax, repeatedly calls another parser the number of times specified.

Example

just!(pub a { "a"; } );
 
repeat!(pub repeat_a_five_times { a; { 5 } } ); 
 
repeat!(pub repeat_a_at_least_five_times { a; { 5, } } ); 

repeat!(pub repeat_a_forever { a; { , } } );
