Struct Header

pub struct Header {
    pub file_type: FileType,
    pub protocol_version: ProtocolVersion,
    pub entry_size: u16,
    pub hash_type: HashType,
}

Structural representation of 32 byte SLEEP headers.

Fields

file_type: FileType

Type of file.

protocol_version: ProtocolVersion

Version of the SLEEP protocol.

entry_size: u16

Size of each piece of data in the file body.

hash_type: HashType

Algorithm used for hashing the content.

Implementations

impl Header

pub fn new(file_type: FileType, entry_size: u16, hash_type: HashType) -> Self

Create a new Header.

pub fn from_vec(buffer: &[u8]) -> Result<Header, Error>

Parse a 32 byte buffer slice into a valid Header.

pub fn to_vec(&self) -> Vec<u8>

Convert a Header into a Vec<u8>. Use this to persist a header back to disk.

pub fn is_bitfield(&self) -> bool

Check whether the header is formatted as a .bitfield.

pub fn is_signatures(&self) -> bool

Check whether the header is formatted as a .signatures.

pub fn is_tree(&self) -> bool

Check whether the header is formatted as a .tree.

Trait Implementations

impl Debug for Header

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

Formats the value using the given formatter.
