Struct unc_sdk::AccountIdRef

pub struct AccountIdRef(/* private fields */);

Account identifier. This is the human readable UTF-8 string which is used internally to index accounts on the network and their respective state.

This is the “referenced” version of the account ID. It is to AccountId what str is to String, and works quite similarly to Path. Like with str and Path, you can’t have a value of type AccountIdRef, but you can have a reference like &AccountIdRef or &mut AccountIdRef.

This type supports zero-copy deserialization offered by serde, but cannot do the same for borsh since the latter does not support zero-copy.

Examples

use unc_account_id::{AccountId, AccountIdRef};
use std::convert::{TryFrom, TryInto};

// Construction
let alice = AccountIdRef::new("alice.unc").unwrap();
assert!(AccountIdRef::new("invalid.").is_err());

Implementations

impl AccountIdRef

pub const MIN_LEN: usize = 2usize

Shortest valid length for a Utility Account ID.

pub const MAX_LEN: usize = 64usize

Longest valid length for a Utility Account ID.

pub fn new<S>(id: &S) -> Result<&AccountIdRef, ParseAccountError>

where S: AsRef<str> + ?Sized,

Construct a &AccountIdRef from a string reference.

This constructor validates the provided ID, and will produce an error when validation fails.

pub const fn new_or_panic(id: &str) -> &AccountIdRef

Construct a &AccountIdRef from with validation at compile time. This constructor will panic if validation fails.

use unc_account_id::AccountIdRef;
const ALICE: &AccountIdRef = AccountIdRef::new_or_panic("alice.unc");

pub fn as_bytes(&self) -> &[u8]

Returns a reference to the account ID bytes.

pub fn as_str(&self) -> &str

Returns a string slice of the entire Account ID.

Examples

use unc_account_id::AccountIdRef;

let carol = AccountIdRef::new("carol.unc").unwrap();
assert_eq!("carol.unc", carol.as_str());

pub fn get_account_type(&self) -> AccountType

Returns AccountType::EthAccount if the AccountId is a 40 characters long hexadecimal prefixed with ‘0x’. Returns AccountType::Un cImplicitAccount if the AccountId is a 64 characters long hexadecimal. Otherwise, returns AccountType::Reserved.

See Implicit-Accounts.

Examples

use unc_account_id::{AccountId, AccountType};

let alice: AccountId = "alice.unc".parse().unwrap();
assert!(alice.get_account_type() == AccountType::Reserved);

let eth_rando = "0xb794f5ea0ba39494ce839613fffba74279579268"
    .parse::<AccountId>()
    .unwrap();
assert!(eth_rando.get_account_type() == AccountType::EthAccount);

let unc_rando = "98793cd91a3f870fb126f66285808c7e094afcfc4eda8a970f6648cdf0dbd6de"
    .parse::<AccountId>()
    .unwrap();
assert!(unc_rando.get_account_type() == AccountType::UtilityAccount);

pub fn is_system(&self) -> bool

Returns true if this AccountId is the system account.

See System account.

Examples

use unc_account_id::AccountId;

let alice: AccountId = "alice.unc".parse().unwrap();
assert!(!alice.is_system());

let system: AccountId = "system".parse().unwrap();
assert!(system.is_system());

pub const fn len(&self) -> usize

Returns the length of the underlying account id string.

pub fn get_parent_account_id(&self) -> Option<&AccountIdRef>

Returns parent’s account id reference

Examples

use unc_account_id::{AccountIdRef, AccountType};
 
let unc: &AccountIdRef = AccountIdRef::new_or_panic("unc");

assert!(unc.get_parent_account_id().is_none());

let implicit: &AccountIdRef = AccountIdRef::new_or_panic("248e104d1d4764d713c4211c13808c8fc887869c580f4178e60538ac5c2a0b26");

assert!(implicit.get_parent_account_id().is_none());
