Trait Implementations

impl Cipher for FxfsCipher

fn encrypt( &self, _ino: u64, _device_offset: u64, file_offset: u64, buffer: &mut [u8], ) -> Result<(), Error>

Encrypts data in the buffer.

fn decrypt( &self, _ino: u64, _device_offset: u64, file_offset: u64, buffer: &mut [u8], ) -> Result<(), Error>

Decrypt the data in buffer.

fn encrypt_filename( &self, object_id: u64, buffer: &mut Vec<u8>, ) -> Result<(), Error>

Encrypts the filename contained in buffer.

fn decrypt_filename( &self, object_id: u64, buffer: &mut Vec<u8>, ) -> Result<(), Error>

Decrypts the filename contained in buffer.

fn hash_code(&self, _raw_filename: &[u8], filename: &str) -> Option<u32>

Returns a hash_code to use. Note in the case of encrypted filenames, takes the raw encrypted bytes.

fn hash_code_casefold(&self, filename: &str) -> u32

Returns a case-folded hash_code to use for ‘filename’.

fn supports_inline_encryption(&self) -> bool

True if supports inline encryption

fn crypt_ctx(&self, _ino: u64, _file_offset: u64) -> Option<(u32, u8)>

If this cipher type supports inline encryption, returns the (dun, slot) value. Else returns None.

fn encrypt_symlink( &self, object_id: u64, buffer: &mut Vec<u8>, ) -> Result<(), Error>

Encrypts the symlink target contained in buffer.

fn decrypt_symlink( &self, object_id: u64, buffer: &mut Vec<u8>, ) -> Result<(), Error>

Decrypts the symlink target contained in buffer.

impl Debug for FxfsCipher

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

Formats the value using the given formatter.
