Enum OptionValue 

pub enum OptionValue {
    Attached {
        token: usize,
        offset: usize,
    },
    Detached {
        token: usize,
    },
}

What: Where an option’s value sits. usize is the index type of lists (siblings: u32, u64); every standard list API indexes with usize. Why: A value is reported by position, never copied, so its bytes stay exactly as given.

In TS you’d write (pseudocode):

type OptionValue = { token: number; offset: number } | { token: number };

Variants

Attached

-mvalue or --message=value: the value starts at byte offset of token.

Fields

token: usize

offset: usize

Detached

-m value: the whole following token is the value.

Fields

token: usize
