Enum ContractPrepareVersion

#[repr(u8)]
pub enum ContractPrepareVersion {
    V0 = 0,
    V1 = 1,
    V2 = 2,
}

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 = 0

Oldest, buggiest version.

Don’t use it unless specifically to support old protocol version.

V1 = 1

Old, slow and buggy version.

Better than V0, but don’t use this nevertheless.

V2 = 2

finite-wasm 0.3.0 based contract preparation code.

Implementations

impl ContractPrepareVersion

pub fn v0() -> ContractPrepareVersion

Trait Implementations

impl Clone for ContractPrepareVersion

fn clone(&self) -> ContractPrepareVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractPrepareVersion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContractPrepareVersion

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for ContractPrepareVersion

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 for ContractPrepareVersion

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for ContractPrepareVersion

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.

impl Copy for ContractPrepareVersion
