Struct CommaSeparated 

pub struct CommaSeparated<'a, T, const MIN: usize = 1> { /* private fields */ }

This is a generic type that can be used for AST nodes representing multiple multiple items separated with commas.

This can be used for any grammar which defines a Comma Separated group ([]#).

The given <T> will be parsed first, followed by a comma. Parsing completes if the comma isn’t found.

As <T> is parsed first, it can have any number of interior commas, however if T should ideally not consume trailing commas, as doing so would likely mean only a single T in this struct.

The effective grammar for this struct is:

<comma-separated>
 │├─╭─ <T> ─╮─ "," ─╭─┤│
    │       ╰───────╯
    ╰───────╯
