Struct near_sdk::AccountId[][src]

pub struct AccountId(_);
Expand description

Account identifier. This is the human readable utf8 string which is used internally to index accounts on the network and their respective state.

Because these IDs have to be validated, they have to be converted from a string with FromStr or TryFrom a compatible type. To skip validation on initialization, AccountId::new_unchecked can be used.

Examples

use near_sdk::AccountId;
use std::convert::{TryFrom, TryInto};

// `FromStr` conversion
let alice: AccountId = "alice.near".parse().unwrap();
assert!("invalid.".parse::<AccountId>().is_err());

let alice_string = "alice".to_string();

// From string with validation
let alice = AccountId::try_from(alice_string.clone()).unwrap();
let alice: AccountId = alice_string.try_into().unwrap();

// Initialize without validating
let alice_unchecked = AccountId::new_unchecked("alice".to_string());
assert_eq!(alice, alice_unchecked);

Implementations

Returns reference to the account ID bytes.

Returns reference to the account ID string.

Caller must ensure that the account id is valid.

Whether Self is u8. NOTE: Vec<u8> is the most common use-case for serialization and deserialization, it’s worth handling it as a special case to improve performance. It’s a workaround for specific Vec<u8> implementation versus generic Vec<T> implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details. Read more
