Struct PosixChunkTransport 

pub struct PosixChunkTransport { /* private fields */ }

Crash-safe POSIX filesystem ChunkTransport for local/USB/SMB mounts.

Chunk layout: {root}/.foxing_cas/chunks/{hash[0..2]}/{full_hash} (2-char shard). All writes use tmp->fsync->rename->dir_fsync for crash safety.

Trait Implementations

impl ChunkTransport for PosixChunkTransport

fn put_chunk<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, hash: &'life1 str, data: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Upload a chunk. Idempotent – re-uploading same hash+data is a no-op for most backends.

fn get_chunk<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Download a chunk by BLAKE3 hash.

fn has_chunk<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check if a chunk exists without downloading it.

fn put_manifest<'life0, 'life1, 'async_trait>( &'life0 self, data: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Upload opaque manifest bytes (replaces any existing manifest).

fn get_manifest<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Download manifest bytes. Returns None if no manifest stored yet.

fn health_check<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Verify transport is accessible and writable.

impl Debug for PosixChunkTransport

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

Formats the value using the given formatter.
