Struct AccountId 

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

A NEAR account identifier.

Valid account IDs:

• Named: “alice.near”, “bob.testnet”, “sub.account.near”
• Implicit (64 hex chars): “0123456789abcdef…”
• EVM implicit (0x + 40 hex chars): “0x1234…”

Examples

use near_kit::AccountId;

let named: AccountId = "alice.testnet".parse().unwrap();
assert!(named.is_named());

let implicit = "0".repeat(64).parse::<AccountId>().unwrap();
assert!(implicit.is_implicit());

Implementations

impl AccountId

pub fn new(s: impl Into<String>) -> Result<Self, ParseAccountIdError>

Parse and validate an account ID.

pub fn parse_lenient(s: impl AsRef<str>) -> Self

Parse an account ID, falling back to unchecked if validation fails.

This is a convenience method for APIs that accept user input where we want to be lenient. If parsing fails, the string is used as-is.

Example

use near_kit::AccountId;

// Valid account parses normally
let valid = AccountId::parse_lenient("alice.near");
assert_eq!(valid.as_str(), "alice.near");

// Invalid account is used as-is (no error)
let invalid = AccountId::parse_lenient("INVALID");
assert_eq!(invalid.as_str(), "INVALID");

pub fn is_implicit(&self) -> bool

Check if this is an implicit account (64 hex chars).

pub fn is_evm_implicit(&self) -> bool

Check if this is an EVM implicit account (0x prefix).

pub fn is_named(&self) -> bool

Check if this is a named account.

pub fn is_top_level(&self) -> bool

Check if this is a top-level account (no dots, like “near” or “testnet”).

pub fn is_sub_account_of(&self, parent: &AccountId) -> bool

Check if this is a subaccount of another account.

pub fn parent(&self) -> Option<AccountId>

Get the parent account (e.g., “sub.alice.near” → “alice.near”).

pub fn as_str(&self) -> &str

Get as string slice.

Trait Implementations

impl AsRef<str> for AccountId

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl BorshDeserialize for AccountId

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

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

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for AccountId

fn serialize<W: Write>(&self, writer: &mut W) -> Result<()>

impl Clone for AccountId

fn clone(&self) -> AccountId

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AccountId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AccountId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AccountId

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for AccountId

type Err = ParseAccountIdError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for AccountId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl IntoContractId for &AccountId

fn into_contract_id(self, _network: Network) -> Result<AccountId, Error>

Resolve this to a contract AccountId for the given network.

impl IntoContractId for AccountId

fn into_contract_id(self, _network: Network) -> Result<AccountId, Error>

Resolve this to a contract AccountId for the given network.

impl PartialEq for AccountId

fn eq(&self, other: &AccountId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AccountId

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for AccountId

type Error = ParseAccountIdError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for AccountId

type Error = ParseAccountIdError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.
