Struct async_fetcher::FetchedState

pub struct FetchedState {
    pub future: Box<dyn Future<Item = Option<Option<FileTime>>, Error = FetchError> + Send>,
    pub download_location: Arc<Path>,
    pub final_destination: Arc<Path>,
    /* private fields */
}

This state manages renaming to the destination, and setting the timestamp of the fetched file.

Fields

future: Box<dyn Future<Item = Option<Option<FileTime>>, Error = FetchError> + Send>

download_location: Arc<Path>

final_destination: Arc<Path>

Implementations

impl FetchedState

pub fn with_checksum<H: Digest>(self, checksum: Arc<str>) -> Self

Apply a Digest-able hash method to the downloaded file, and compare the checksum to the given input.

pub fn then_rename(
    self
) -> CompletedState<impl Future<Item = (), Error = FetchError> + Send>

Replaces and renames the fetched file, then sets the file times.

pub fn then_process<F>(
    self,
    construct_writer: F
) -> CompletedState<impl Future<Item = (), Error = FetchError> + Send>where
    F: Fn(SyncFile) -> Result<Box<dyn Write + Send>> + Send,

Processes the fetched file, storing the output to the destination, then setting the file times.

Use this to decompress an archive if the fetched file was an archive.

pub fn into_future(
    self
) -> impl Future<Item = Option<Option<FileTime>>, Error = FetchError> + Send
