Struct FsByteSource 

pub struct FsByteSource { /* private fields */ }

A source that is a path to a file on the filesystem. The contents of the file are cached on the first call to get(), and can be refreshed by calling the reload() method.

Implementations

impl FsByteSource

pub fn new(path: Path) -> Self

Creates an FsBytesSource from a path on the filesystem

pub fn reload(&mut self)

Empties the cache, triggering a reload of the file on the next call to get. Note that this function does not perform any file I/O.

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

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

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

Returns the bytes stored at the path

pub fn path(&self) -> &Path

Returns the path where the key is stored
