[][src]Struct asuran::repository::backend::multifile::manifest::Manifest

pub struct Manifest {
    input: Sender<ManifestCommand>,
    path: String,

A message-passing handle to a running manifest


  1. In order to ensure that file locks are freed and data is writeen properly, you must ensure that you call the close method on the manifest before your program terminates


input: Sender<ManifestCommand>path: String


impl Manifest[src]

pub fn open(
    repository_path: impl AsRef<Path>,
    chunk_settings: Option<ChunkSettings>,
    key: &Key,
    queue_depth: usize
) -> Result<Manifest>

Opens and reads the manifest, creating it if it does not exist

Note that the repository path is the root path of the repository, not the path of the index folder.

This method will create the manifest folder if it does not exist.

Files whose names are not strictly base 10 integers are ignored, and will not be added to the state or written to.

This method only creates the event loop, the actual manifest is created by InternalManifest::open

This method can optinally set the chunksettings for the manifest, but it is an error to not provide chunk settings if the manifest has not been created yet


Will return Err if

  1. The manifest folder does not exist and creating it failed
  2. There are no unlocked manifest folders and creating one fails
  3. There is a file called "manifest" in the repository folder
  4. Some other IO error (shuch as lack of permissions) occurs
  5. The path contains non-utf8 characters


  1. Return an error if deserializing a transaciton fails before the end of the file is reached
  2. This function can currently panic if we have to create a new manifest file, but someone else creates the same file we are trying to first.
