Enum polkadot_availability_recovery::RecoveryStrategy

pub enum RecoveryStrategy {
    BackersFirstAlways,
    BackersFirstIfSizeLower(usize),
    ChunksAlways,
    BypassAvailabilityStore,
}

The strategy we use to recover the PoV.

Variants

BackersFirstAlways

We always try the backing group first, then fallback to validator chunks.

BackersFirstIfSizeLower(usize)

We try the backing group first if PoV size is lower than specified, then fallback to validator chunks.

ChunksAlways

We always recover using validator chunks.

BypassAvailabilityStore

Do not request data from the availability store. This is the useful for nodes where the availability-store subsystem is not expected to run, such as collators.

Implementations

impl RecoveryStrategy

pub fn needs_backing_group(&self) -> bool

Returns true if the strategy needs backing group index.

pub fn pov_size_limit(&self) -> Option<usize>

Returns the PoV size limit in bytes for BackersFirstIfSizeLower strategy, otherwise None.

Trait Implementations

impl Clone for RecoveryStrategy

fn clone(&self) -> RecoveryStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<RecoveryStrategy> for RecoveryStrategy

fn eq(&self, other: &RecoveryStrategy) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
