Struct Footer 

pub struct Footer {
    pub checksum_type: ChecksumType,
    pub metaindex_handle: BlockHandle,
    pub index_handle: BlockHandle,
    pub format_version: u32,
    pub base_context_checksum: Option<u32>,
}

Fields

checksum_type: ChecksumType

metaindex_handle: BlockHandle

index_handle: BlockHandle

format_version: u32

base_context_checksum: Option<u32>

Base context checksum used as entropy source for footer checksum calculation. Only present in format version 6 and higher. This value is combined with the footer’s file offset to create a unique checksum modifier, preventing block reuse attacks by ensuring checksums are position-dependent.

Implementations

impl Footer

pub fn read_from<R: Read + Seek>(reader: &mut R) -> Result<Self>

pub fn decode_from_bytes(data: &[u8], input_offset: u64) -> Result<Self>

pub fn encode_to_bytes(&self, offset: u64) -> Result<Vec<u8>>

Trait Implementations

impl Clone for Footer

fn clone(&self) -> Footer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Footer

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

Formats the value using the given formatter.

impl PartialEq for Footer

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

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

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

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