    pub target_bytes_downloaded: u64,
    pub speeds: Vec<f64>,
}

Structure representing the current state of a file or directory on fud. It is used in most FudEvent.

Fields

hash: Hash

Resource hash (used as key in the DHT)

rtype: ResourceType

Resource type (file or directory)

path: PathBuf

Path of the resource on the filesystem

status: ResourceStatus

Current status of the resource

file_selection: FileSelection

The files the user wants to download

total_chunks_count: u64

Total number of chunks

target_chunks_count: u64

Number of chunks we want to download

total_chunks_downloaded: u64

Number of chunks we already downloaded

target_chunks_downloaded: u64

Number of chunks we already downloaded, but only those we want to download on the last fetch request

total_bytes_size: u64

Total size (in bytes) of the resource

target_bytes_size: u64

Data (in bytes) we want to download

total_bytes_downloaded: u64

Data (in bytes) we already downloaded

target_bytes_downloaded: u64

Data (in bytes) we already downloaded, but only data we want to download on the last fetch request

speeds: Vec<f64>

Recent speeds in bytes/sec, used to compute the download ETA.

Implementations

impl Resource

pub fn new( hash: Hash, rtype: ResourceType, path: &Path, status: ResourceStatus, file_selection: FileSelection, ) -> Self

pub fn get_eta(&self) -> u64

Computes and returns download ETA in seconds using the speeds list.

pub fn get_selected_files(&self, chunked: &ChunkedStorage) -> Vec<PathBuf>

Returns the list of selected files (absolute paths).

pub fn get_selected_chunks(&self, chunked: &ChunkedStorage) -> HashSet<Hash>

Returns the (sub)set of chunk hashes in a ChunkedStorage for a file selection.

pub fn get_selected_bytes( &self, chunked: &ChunkedStorage, chunk: &[u8], ) -> usize

Returns the number of bytes we want from a chunk (depends on the file selection).

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Resource

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

Formats the value using the given formatter.

impl From<JsonValue> for Resource

fn from(value: JsonValue) -> Self

Converts to this type from the input type.

impl From<Resource> for JsonValue

fn from(rs: Resource) -> JsonValue
