Struct ParsedOptions 

pub struct ParsedOptions {
    pub occurrences: Vec<Occurrence>,
    pub wrapper: Vec<WrapperOccurrence>,
    pub unknown: Vec<usize>,
    pub leading: Vec<usize>,
    pub boundary: Boundary,
}

What: Everything learned from one argument region. Vec<T> is an owned, growable list (siblings: &[T], a borrowed view, and [T; N], a fixed-size array). Why: The result outlives the scan and its lengths are unknown beforehand, so it owns lists.

In TS you’d write (pseudocode):

type ParsedOptions = { occurrences: Occurrence[]; wrapper: WrapperOccurrence[];
  unknown: number[]; leading: number[]; boundary: Boundary };

Fields

occurrences: Vec<Occurrence>

Declared options in the order Git applies them.

wrapper: Vec<WrapperOccurrence>

Wrapper-only flags found in option position.

unknown: Vec<usize>

Tokens holding an undeclared option, only under keep_unknown.

leading: Vec<usize>

Non-option tokens before the boundary.

boundary: Boundary

How option parsing ended.
