Struct redact_crypto::FsByteSource

pub struct FsByteSource { /* fields omitted */ }

A source that is a path to a file on the filesystem. Bytes are loaded on creation of the FsBytesSource. Bytes can be refreshed from the filesystem by calling reload. To get fresh bytes on every call of get, use an UncachedFsBytesSource.

Implementations

impl FsByteSource

pub fn new(path: Path) -> Result<Self, CryptoError>

Creates an FsBytesSource from a path on the filesystem

pub fn reload(&mut self) -> Result<(), CryptoError>

Re-reads the file and stores its bytes in memory

pub fn set(&mut self, value: &[u8]) -> Result<(), CryptoError>

Re-writes the file at the path to the given bytes

pub fn get(&self) -> Result<&[u8], CryptoError>

Returns the bytes stored at the path

pub fn path(&self) -> &Path

Returns the path where the key is stored
