Struct CardRewritePlan 

pub struct CardRewritePlan {
    pub header: Header,
    pub before: (u64, u64),
    pub after: (u64, u64),
    pub card_offset: u64,
    pub new_len: u64,
}

What a card rewrite does to a file’s layout.

Fields

header: Header

The new header: every section offset fixed, metadata and build info at their new lengths. The content hash is still the old one — rewrite_card writes the new one once it has folded it.

before: (u64, u64)

The span of the old file copied verbatim before the new card, [HEADER_LEN, card_start) — empty on every file the writers produce; non-empty when a section was laid out ahead of the card.

after: (u64, u64)

The span of the old file copied verbatim after the new card, [card_end, file_len).

card_offset: u64

Where the new metadata section starts (build info follows it).

new_len: u64

The rewritten file’s length.
