Macro syn::many0

macro_rules! many0 {
    ($i:expr, $submac:ident!( $($args:tt)* )) => { ... };
    ($i:expr, $f:expr) => { ... };
}

Parse zero or more values using the given parser.

• Syntax: many0!(THING)
• Output: Vec<THING>

You may also be looking for:

• call!(Punctuated::parse_separated) - zero or more values with separator
• call!(Punctuated::parse_separated_nonempty) - one or more values
• call!(Punctuated::parse_terminated) - zero or more, allows trailing separator
• call!(Punctuated::parse_terminated_nonempty) - one or more
