Struct AccountId

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

Utility Account Identifier.

This is a unique, syntactically valid, human-readable account identifier on the Utility network.

See the crate-level docs for information about validation.

Also see Error kind precedence.

Examples

use unc_account_id::AccountId;

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

assert!("ƒelicia.unc".parse::<AccountId>().is_err()); // (ƒ is not f)

Implementations

impl AccountId

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 validate(account_id: &str) -> Result<(), ParseAccountError>

Validates a string as a well-structured Utility Account ID.

Checks Account ID validity without constructing an AccountId instance.

Examples

use unc_account_id::{AccountId, ParseErrorKind};

assert!(AccountId::validate("alice.unc").is_ok());

assert!(
  matches!(
    AccountId::validate("ƒelicia.unc"), // fancy ƒ!
    Err(err) if err.kind() == &ParseErrorKind::InvalidChar
  )
);

Error kind precedence

If an Account ID has multiple format violations, the first one would be reported.

Examples

use unc_account_id::{AccountId, ParseErrorKind};

assert!(
  matches!(
    AccountId::validate("A__ƒƒluent."),
    Err(err) if err.kind() == &ParseErrorKind::InvalidChar
  )
);

assert!(
  matches!(
    AccountId::validate("a__ƒƒluent."),
    Err(err) if err.kind() == &ParseErrorKind::RedundantSeparator
  )
);

assert!(
  matches!(
    AccountId::validate("aƒƒluent."),
    Err(err) if err.kind() == &ParseErrorKind::InvalidChar
  )
);

assert!(
  matches!(
    AccountId::validate("affluent."),
    Err(err) if err.kind() == &ParseErrorKind::RedundantSeparator
  )
);

Methods from Deref<Target = AccountIdRef>

pub const MIN_LEN: usize = 2usize

pub const MAX_LEN: usize = 64usize

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 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");
