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.
Caller must ensure that the account id is valid.
