Fields

signature: [u8; 64]

NaCl signature of header data

public_key: [u8; 32]

NaCl public key used to generate signature

blake3: [u8; 32]

Blake3 sum of entry data

count: u64

Count of Entry structs, which immediately follow

Methods

impl Header

pub fn new<'a>(
    data: &'a [u8],
    public_key: &PublicKey
) -> Result<&'a Header, Error>

Parse header from raw header data and verify using public key

pub unsafe fn new_unchecked<'a>(data: &'a [u8]) -> Result<&'a Header, Error>

Parse header from raw header data without verification

pub fn entries_size(&self) -> Result<u64, Error>

Retrieve the size of the entries

pub fn total_size(&self) -> Result<u64, Error>

Retrieve the size of the Header and its entries

pub fn entries<'a>(&self, data: &'a [u8]) -> Result<&'a [Entry], Error>

Parse entries from raw entries data and verify using blake3

pub unsafe fn entries_unchecked<'a>(
    data: &'a [u8]
) -> Result<&'a [Entry], Error>

Parse entries from raw entries data without verification
