Enum DeterministicAccountStateInit 

#[repr(u8)]
pub enum DeterministicAccountStateInit {
    V1(DeterministicAccountStateInitV1),
}

State initialization data for NEP-616 deterministic accounts.

The account ID is derived from: "0s" + hex(keccak256(borsh(state_init))[12..32])

Variants

V1(DeterministicAccountStateInitV1)

Version 1 of the state init format.

Implementations

impl DeterministicAccountStateInit

pub fn derive_account_id(&self) -> AccountId

Derive the deterministic account ID from this state init.

The account ID is derived as: "0s" + hex(keccak256(borsh(state_init))[12..32])

This produces a 42-character account ID that:

• Starts with “0s” prefix (distinguishes from Ethereum implicit accounts “0x”)
• Followed by 40 hex characters (20 bytes from the keccak256 hash)

Example

use near_kit::types::{DeterministicAccountStateInit, DeterministicAccountStateInitV1, GlobalContractIdentifier, CryptoHash};
use std::collections::BTreeMap;

let state_init = DeterministicAccountStateInit::V1(DeterministicAccountStateInitV1 {
    code: GlobalContractIdentifier::CodeHash(CryptoHash::default()),
    data: BTreeMap::new(),
});

let account_id = state_init.derive_account_id();
assert!(account_id.as_str().starts_with("0s"));
assert_eq!(account_id.as_str().len(), 42);

Trait Implementations

impl BorshDeserialize for DeterministicAccountStateInit

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for DeterministicAccountStateInit

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for DeterministicAccountStateInit

fn clone(&self) -> DeterministicAccountStateInit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeterministicAccountStateInit

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

impl EnumExt for DeterministicAccountStateInit

fn deserialize_variant<__R: Read>( reader: &mut __R, variant_tag: u8, ) -> Result<Self, Error>

Deserialises given variant of an enum from the reader.

impl PartialEq for DeterministicAccountStateInit

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