Struct `ExtendedFileOptions`

pub struct ExtendedFileOptions { /* private fields */ }

The Extension for Extra Data and Central Extra Data

Implementations

`impl ExtendedFileOptions`

fn add_extra_data<D: AsRef<[u8]>>(&mut self, header_id: u16, data: D, central_only: bool) -> ZipResult<()>

Adds an extra data field, unless we detect that it's invalid.

Parameters

header_id – The 2‑byte identifier of the ZIP extra field to add. This value determines the type/format of data and should either be one of the standard ZIP extra field IDs defined by the ZIP specification or an application‑specific (vendor) ID.
data – The raw payload for the extra field, without the leading header ID or length; those are derived from header_id and data.len() and written automatically.
central_only – Controls where the extra field is stored:
- When true, the field is appended only to the central directory extra data (central_extra_data), and the corresponding local file header is left unchanged.
- When false, the field is appended to the local file header extra data (extra_data) and may also be reflected in the central directory, depending on how the ZIP is written.

The combined size of all extra data (local + central) must not exceed u16::MAX. If adding this field would exceed that limit or produce an invalid extra data structure, an error is returned and no data is added.
