subspace_farmer::single_disk_farm

Struct SingleDiskFarm

source 
pub struct SingleDiskFarm { /* private fields */ }
Expand description

Single disk farm abstraction is a container for everything necessary to plot/farm with a single disk.

Farm starts operating during creation and doesn’t stop until dropped (or error happens).

Implementations§

source§

impl SingleDiskFarm

source

pub const PLOT_FILE: &'static str = "plot.bin"

Name of the plot file

source

pub const METADATA_FILE: &'static str = "metadata.bin"

source

pub async fn new<NC, PosTable>( options: SingleDiskFarmOptions<'_, NC>, farm_index: usize, ) -> Result<Self, SingleDiskFarmError>

Wipe everything that belongs to this single disk farm

source

pub fn scrub( directory: &Path, disable_farm_locking: bool, target: ScrubTarget, dry_run: bool, ) -> Result<(), SingleDiskFarmScrubError>

Check the farm for corruption and repair errors (caused by disk errors or something else), returns an error when irrecoverable errors occur.
