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
Caller must ensure that the account id is valid.

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