Enum polkadot_node_subsystem::messages::PreCheckOutcome

pub enum PreCheckOutcome {
    Valid,
    Invalid,
    Failed,
}

The outcome of the candidate-validation’s PVF pre-check request.

Variants

Valid

The PVF has been compiled successfully within the given constraints.

Invalid

The PVF could not be compiled. This variant is used when the candidate-validation subsystem can be sure that the PVF is invalid. To give a couple of examples: a PVF that cannot be decompressed or that does not represent a structurally valid WebAssembly file.

Failed

This variant is used when the PVF cannot be compiled but for other reasons that are not included into PreCheckOutcome::Invalid. This variant can indicate that the PVF in question is invalid, however it is not necessary that PVF that received this judgement is invalid.

For example, if during compilation the preparation worker was killed we cannot be sure why it happened: because the PVF was malicious made the worker to use too much memory or its because the host machine is under severe memory pressure and it decided to kill the worker.

Trait Implementations

impl Debug for PreCheckOutcome

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

Formats the value using the given formatter.

impl PartialEq for PreCheckOutcome

fn eq(&self, other: &PreCheckOutcome) -> 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.
