Struct BuildInfoPlan 

pub struct BuildInfoPlan {
    pub header: [u8; 1024],
    pub insert: u64,
    pub tail_start: u64,
    pub new_len: u64,
}

Everything needed to splice a build-info section into a finished file without holding the file in memory: the rewritten header, where the section goes, and where the bytes that do not move resume.

See plan_build_info for what the fields mean together: the build-info section always follows the metadata section, so the layout is [header][metadata][build info][everything else, verbatim] — or, for a card placed after the data, [header][data…][metadata][build info][footer].

Fields

header: [u8; 1024]

The header bytes to write at offset 0.

insert: u64

Offset the new section is written at: the end of the metadata section (the length of the unchanged prefix up to and including the card).

tail_start: u64

Offset in the old file where the bytes that do not move resume. The span insert..tail_start is the old build-info section, if any, and is the only part of the old file the new one drops.

new_len: u64

Length of the file this plan produces.
