Struct devol_accounts_kit::dvl_error::DvlError

pub struct DvlError { /* private fields */ }

Implementations

impl DvlError

pub fn new_with_account(account: AccountTag, error: ContractError) -> Self

Creates a new ContractErrorDetails with a specified error and associated account.

pub fn new(error: ContractError) -> Self

Creates a new ContractErrorDetails with a specified error without associating an account.

pub fn encode(&self) -> u32

Encodes the error details into a 32-bit integer for on-chain error handling.

The error code is a 32-bit unsigned integer where:

• The most significant bit (MSB) is always set to 1 to indicate a new error system.
• The next 3 bits (from MSB) are reserved for future use and are currently set to 0.
• The following 8 bits represent the account identifier if provided, or are set to 0.
• The least significant 16 bits represent the ContractError code.

Arguments

• error - A ContractError enumeration representing the specific error.
• account - An optional Account enumeration representing the account involved in the error, if applicable.

Returns

A 32-bit unsigned integer encoding the error and account information according to the rules described.

Layout

31 30 29 25 24 16 15 0 +––+––+—––+——————————+––––––––––––––––+ | 1 | A | 0 0 0 | Account ID (if provided) | ContractError Code | +––+––+—––+——————————+––––––––––––––––+

1 = MSB, always set to indicate a new error system. A = Account-related flag (set to 1 if the error is account-specific, 0 otherwise). Reserved = Currently unused bits, set to 0. Account ID = 8-bit identifier for the account, shifted into bits 23 through 16. ContractError Code = 16-bit error code, occupying the least significant bits.

Trait Implementations

impl Clone for DvlError

fn clone(&self) -> DvlError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DvlError

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

Formats the value using the given formatter.

impl Display for DvlError

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

Formats the value using the given formatter.

impl Error for DvlError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
