Struct sn_client::FilesDownload
source · pub struct FilesDownload { /* private fields */ }
Expand description
FilesDownload
provides functionality for downloading chunks with support for retries and queuing.
This struct is not cloneable. To create a new instance with default configuration, use the new
function.
To modify the configuration, use the provided setter methods (set_...
functions).
Implementations§
source§impl FilesDownload
impl FilesDownload
sourcepub fn new(files_api: FilesApi) -> Self
pub fn new(files_api: FilesApi) -> Self
Creates a new instance of FilesDownload
with the default configuration.
To modify the configuration, use the provided setter methods (set_...
functions).
sourcepub fn set_batch_size(self, batch_size: usize) -> Self
pub fn set_batch_size(self, batch_size: usize) -> Self
Sets the default batch size that determines the number of chunks that are downloaded in parallel
By default, this option is set to the constant BATCH_SIZE: usize = 64
.
sourcepub fn set_show_holders(self, show_holders: bool) -> Self
pub fn set_show_holders(self, show_holders: bool) -> Self
Sets the option to display the holders that are expected to be holding a chunk during verification.
By default, this option is set to false.
sourcepub fn set_retry_strategy(self, retry_strategy: RetryStrategy) -> Self
pub fn set_retry_strategy(self, retry_strategy: RetryStrategy) -> Self
Sets the RetryStrategy to increase the re-try on failure attempts.
By default, this option is set to RetryStrategy::Quick
sourcepub fn get_events(&mut self) -> Receiver<FilesDownloadEvent>
pub fn get_events(&mut self) -> Receiver<FilesDownloadEvent>
Returns a receiver for file download events. This method is optional and the download process can be performed without it.
sourcepub async fn download_from(
&mut self,
address: ChunkAddress,
position: usize,
length: usize,
) -> Result<Bytes, Error>
pub async fn download_from( &mut self, address: ChunkAddress, position: usize, length: usize, ) -> Result<Bytes, Error>
Download bytes from the network. The contents are spread across multiple chunks in the network. This function invokes the self-encryptor and returns the data that was initially stored.
Takes position
and length
arguments which specify the start position
and the length of bytes to be read.
Passing 0
to position reads the data from the beginning,
and the length
is just an upper limit.
pub async fn download_from_inner( &mut self, address: ChunkAddress, position: usize, length: usize, ) -> Result<Bytes, Error>
sourcepub async fn download_file(
&mut self,
address: ChunkAddress,
data_map_chunk: Option<Chunk>,
) -> Result<Bytes, Error>
pub async fn download_file( &mut self, address: ChunkAddress, data_map_chunk: Option<Chunk>, ) -> Result<Bytes, Error>
Download a file from the network and get the decrypted bytes. If the data_map_chunk is not provided, the DataMap is fetched from the network using the provided address.
sourcepub async fn download_file_to_path(
&mut self,
address: ChunkAddress,
data_map_chunk: Option<Chunk>,
path: PathBuf,
) -> Result<(), Error>
pub async fn download_file_to_path( &mut self, address: ChunkAddress, data_map_chunk: Option<Chunk>, path: PathBuf, ) -> Result<(), Error>
Download a file from the network and write it to the provided path. If the data_map_chunk is not provided, the DataMap is fetched from the network using the provided address.
