Enum near_vm_logic::StackLimiterVersion

pub enum StackLimiterVersion {
    V0,
    V1,
}

Our original code for limiting WASM stack was buggy. We fixed that, but we still have to use old (V0) limiter for old protocol versions.

This struct here exists to enforce that the value in the config is either 0 or 1. We could have used a bool instead, but there’s a chance that our current impl isn’t perfect either and would need further tweaks in the future.

Variants

V0

Old, buggy version, don’t use it unless specifically to support old protocol version.

V1

What we use in today’s protocol.

Implementations

impl StackLimiterVersion

pub fn v0() -> StackLimiterVersion

Trait Implementations

impl Clone for StackLimiterVersion

fn clone(&self) -> StackLimiterVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StackLimiterVersion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StackLimiterVersion

fn deserialize<D>( deserializer: D ) -> Result<StackLimiterVersion, <D as Deserializer<'de>>::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for StackLimiterVersion

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<StackLimiterVersion> for StackLimiterVersion

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

impl Serialize for StackLimiterVersion

fn serialize<S>( &self, serializer: S ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>where S: Serializer,

Serialize this value into the given Serde serializer.
