Struct MultiDirectoryFileAccess 

pub struct MultiDirectoryFileAccess { /* private fields */ }

A FileAccess that searches multiple directories for files.

When reading a file, directories are searched in order: primary first, then each additional search directory. The first directory containing the file wins. Writes always go to the primary directory.

Implementations

impl MultiDirectoryFileAccess

pub fn new( primary_dir: PathBuf, search_dirs: Vec<PathBuf>, par2_set: &Par2FileSet, ) -> Self

Create a new multi-directory accessor.

primary_dir is the main directory for reads and writes. search_dirs are additional directories to search when a file isn’t found in the primary (e.g., directories from duplicate NZB downloads).

Trait Implementations

impl FileAccess for MultiDirectoryFileAccess

fn read_file_range( &self, file_id: &FileId, offset: u64, len: u64, ) -> Result<Vec<u8>>

Read a range of bytes from a file identified by its FileId.

fn read_file_range_into( &self, file_id: &FileId, offset: u64, dst: &mut [u8], ) -> Result<usize>

Read bytes into a caller-provided buffer, returning the number of bytes read.

fn open_sequential_reader( &self, file_id: &FileId, ) -> Result<Option<Box<dyn Read>>>

Open a forward-only reader for hot paths that consume a whole file from offset 0.

fn open_range_reader( &self, file_id: &FileId, ) -> Result<Option<Box<dyn FileRangeReader>>>

Open a reusable seekable reader for range-oriented repair input.

fn file_exists(&self, file_id: &FileId) -> bool

Check if a file exists on disk.

fn file_length(&self, file_id: &FileId) -> Option<u64>

Get the actual length of a file on disk.

fn read_file(&self, file_id: &FileId) -> Result<Vec<u8>>

Read the entire file content.

fn write_file_range( &mut self, file_id: &FileId, offset: u64, data: &[u8], ) -> Result<()>

Write data to a file at the given offset.
