Struct 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>

Trait Implementations

impl Clone for SectorHeader

fn clone(&self) -> SectorHeader

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SectorHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SectorHeader

fn default() -> SectorHeader

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SectorHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for SectorHeader

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SectorHeader

fn cmp(&self, other: &SectorHeader) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SectorHeader

fn eq(&self, other: &SectorHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SectorHeader

fn partial_cmp(&self, other: &SectorHeader) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SectorHeader

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
