pub fn read_overflow_chain(
pager: &Pager,
first_page: u32,
total_body_len: u64,
) -> Result<Vec<u8>>Expand description
Walks an overflow chain starting at first_page and concatenates its
payload bytes. Reads exactly total_body_len bytes — a mismatch between
what the chain carries and what the OverflowRef claims is a corruption
error.
