Enum EIVersion

pub enum EIVersion {
    V1_0,
    V1_1,
    V1_2,
    V1_3,
    V1_4,
    V1_5,
}

The version of the SC environment interface (EI), it deals with the VM hooks available at a certain point in time.

It is not tied to the version of the VM, hence the different numbering.

Variants

V1_0

This is not necessarily the first version of the EI, but rather the oldest version when we started keeping track of the EI.

V1_1

New hooks added in Q4 2021.

Added a few more managed type & ESDT utilities.

V1_2

New hooks added in Q2 2022. This is the EI version of VM 1.4.

This is the version currently on mainnet.

Added:

• more managed type conversions
• more managed crypto hooks
• big floats
• some managed ESDT properties.

V1_3

Latest VM Hooks version, released with VM 1.5 in January 2024: https://multiversx.com/release/release-sirius-v1-6-7

Implementations

impl EIVersion

pub fn from_name(name: &str) -> Option<EIVersion>

Trait Implementations

impl Clone for EIVersion

fn clone(&self) -> EIVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EIVersion

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

Formats the value using the given formatter.

impl Default for EIVersion

fn default() -> EIVersion

Returns the “default value” for a type.

impl PartialEq for EIVersion

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