Struct runefs::SectorHeader

pub struct SectorHeader {
    pub archive_id: u32,
    pub chunk: usize,
    pub next: usize,
    pub index_id: u8,
}

A section header containing validation and its next sector.

Fields

archive_id: u32

chunk: usize

next: usize

index_id: u8

Implementations

impl<'a> SectorHeader

pub fn new(
    buffer: &'a [u8],
    header_size: &SectorHeaderSize
) -> Result<(&'a [u8], Self), Error>

Constructs a sector header from the given buffer.

Each sector is guaranteed to have a length of 520 bytes. The header size will be either 8 or 10 bytes, making the data size either 512 or 510 bytes respectively. Only when the archive id exceeds u16::MAX will the header size be expanded (meaning a 10 byte header).

Errors

The header buffer needs to be exactly SectorHeaderSize, otherwise you will get a parser error.

pub const fn validate(
    &self,
    archive_id: u32,
    chunk: usize,
    index_id: u8
) -> Result<(), ReadError>
