Implementations

impl FileManager

pub fn new(data_dir: &Path) -> Result<Self>

data_dir is huddle’s per-user data directory; the cache lives underneath at <data_dir>/files/cache.

pub fn cache_dir(&self) -> &Path

pub fn cache_path(&self, file_id: &str) -> PathBuf

pub fn read_cache(&self, file_id: &str) -> Result<Vec<u8>>

Read a previously-completed transfer’s bytes from cache.

pub fn prepare_outgoing_from_path(&self, path: &Path) -> Result<OutgoingPlan>

Build a transfer plan from an on-disk file.

pub fn prepare_outgoing_from_bytes( &self, name: &str, mime: Option<String>, bytes: Vec<u8>, ) -> Result<OutgoingPlan>

Build a transfer plan from an in-memory blob (useful for the encrypted path, where the caller pre-encrypts a file).

pub fn accept_chunk( &self, file_id: &str, chunk_index: u32, total_chunks: u32, data: Vec<u8>, expected_size: u64, ) -> Result<Option<CompletedFile>>

Accept one chunk of an incoming transfer. Returns Some only on the last chunk that completes the file (after SHA-256 verification).

pub fn cancel_incoming(&self, file_id: &str)

Drop any partial state for an incoming transfer.

pub fn progress(&self, file_id: &str) -> Option<(u64, u64)>

Bytes received so far for an in-progress transfer.

pub fn write_to_downloads( &self, target_name: &str, bytes: &[u8], ) -> Result<PathBuf>

Copy bytes into the platform’s Downloads folder under target_name (with -N suffix on collision). Returns the absolute path of the saved file.
