Enum WasmVersion 

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

Version of the module. This determines the chain API that the module can access.

Variants

V0 = 0

The initial smart contracts version. This has a simple state API that has very limited capacity. V0 contracts also use message-passing as the interaction method.

V1 = 1

V1 contracts were introduced with protocol version 4. In comparison to V0 contracts they use synchronous calls as the interaction method, and they have access to a more fine-grained state API allowing for unlimited (apart from NRG costs) state size.

Trait Implementations

impl Clone for WasmVersion

fn clone(&self) -> WasmVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmVersion

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

Formats the value using the given formatter.

impl Default for WasmVersion

V0 is the default version of smart contracts.

fn default() -> WasmVersion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WasmVersion

fn deserialize<__D>( __deserializer: __D, ) -> Result<WasmVersion, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for WasmVersion

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

Formats the value using the given formatter.

impl FromStr for WasmVersion

type Err = WasmVersionParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<WasmVersion, <WasmVersion as FromStr>::Err>

Parses a string s to return a value of this type.

impl Ord for WasmVersion

fn cmp(&self, other: &WasmVersion) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for WasmVersion

fn eq(&self, other: &WasmVersion) -> 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 PartialOrd for WasmVersion

fn partial_cmp(&self, other: &WasmVersion) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for WasmVersion

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 TryFrom<u8> for WasmVersion

type Error = U8WasmVersionConvertError

The type returned in the event of a conversion error.

fn try_from( value: u8, ) -> Result<WasmVersion, <WasmVersion as TryFrom<u8>>::Error>

Performs the conversion.
