Function gix_index::extension::end_of_index_entry::write_to

pub fn write_to(
    out: impl Write,
    hash_kind: Kind,
    offset_to_extensions: u32,
    prior_extensions: impl IntoIterator<Item = (Signature, u32)>,
) -> Result<(), Error>

Write this extension to out and generate a hash of hash_kind over all prior_extensions which are specified as (signature, size) pair. one_past_entries is the offset to the first byte past the entries, which is also the first byte of the signature of the first extension in prior_extensions. Note that prior_extensions must have been written prior to this one, as the name suggests, allowing this extension to be the last one in the index file.

Even if there are no prior_extensions, this extension will be written unconditionally.
