Struct fencryption_lib::file_header::FileHeader

pub struct FileHeader { /* private fields */ }

Manipulate (create/parse) file headers.

A pack file header is made up of 12 bytes:

• 4 bytes representing the length of the associated path
• 8 bytes representing the length of the associated file

The maximum file length that can be stored in the header is about 18.4 Terabytes.

Implementations

impl FileHeader

pub fn new<P1, P2>(file_path: P1, dir_path: P2) -> Result<FileHeader, ErrorKind>where
    P1: AsRef<Path>,
    P2: AsRef<Path>,

Creates a pack file header.

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

Returns the current header as a vector of bytes

pub fn path_len_usize(&self) -> Result<usize, ErrorKind>

pub fn file_len_u64(&self) -> u64

Trait Implementations

impl TryFrom<&[u8; 12]> for FileHeader

fn try_from(bytes: &[u8; 12]) -> Result<Self, Self::Error>

Extracts a file header from an array of 12 bytes.

type Error = ErrorKind

The type returned in the event of a conversion error.
