Bitpeace

Companion object Bitpeace

trait Bitpeace[F[_]] extends AnyRef

A store for binary data.

Binary data is given as a stream of bytes. The stream is saved in chunks, where each chunk is stored into a blob object (in contrast to use one blob for the whole data). This makes it possible to effectively retrieve partial content.

abstract def addChunk(chunk: FileChunk, chunksize: Int, totalChunks: Int, hint: MimetypeHint): Stream[F, Outcome[FileMeta]]
Adds a new chunk of data to a file.
Adds a new chunk of data to a file.
Creates or updates the corresponding FileMeta record and returns it. This is useful if you get chunks of data in some random order.
If the chunk already exists with correct length, the return value is wrapped in Outcome.Unmodified and the given chunk is not written, otherwise a Outcome#Created is returned and the chunk is stored.
abstract def chunkExists(id: String, chunkNr: Long): Stream[F, Boolean]
Return whether a file with given id has a chunk with the given chunkNr.
abstract def chunkExistsRemove(id: String, chunkNr: Long, chunkLength: Long): Stream[F, Boolean]

chunkExists}} but also checks the chunk size. If a chunk
with different size exists, it is removed and {{{false
```
is returned. with different size exists, it is removed and {{{false }}} returned.
abstract def count: Stream[F, Long]
Count all FileMeta rows.
abstract def delete(id: String): Stream[F, Boolean]
Deletes the file data and meta-data.
abstract def exists(id: String): Stream[F, Boolean]
Return whether a file with a given id exists.
abstract def fetchData(range: RangeDef): Pipe[F, FileMeta, Byte]
Fetch data using one connection per chunk.
Fetch data using one connection per chunk. So connections are closed immediately after reading a chunk.
abstract def fetchData2(range: RangeDef): Pipe[F, FileMeta, Byte]
Fetch data using one connection for the whole stream.
Fetch data using one connection for the whole stream. It is closed once the stream terminates.
abstract def get(id: String): Stream[F, Option[FileMeta]]
Return meta data about one file.
abstract def getChunks(id: String, offset: Option[Int] = None, limit: Option[Int] = None): Stream[F, FileChunk]
Get chunks using one connection.
