Errors for parameter value validation and arithmetic.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Negative

Value must be non-negative for this parameter type.

Fields

param: ParamKind

DivisionByZero

Division by zero.

Fields

param: ParamKind

Overflow

Arithmetic overflow occurred.

Fields

param: ParamKind

Underflow

Arithmetic underflow resulted in negative value for unsigned type.

Fields

param: ParamKind

InvalidFloat = 5

Conversion from f64 failed.

InvalidFormat

Failed to parse string into decimal value.

Fields

param: ParamKind

input: Box<str>

InvalidPrice = 7

Price has invalid value.

InvalidLeverage = 8

Leverage has invalid value.

AssetEmpty = 9

Asset identifier is empty.

AccountIdEmpty = 10

Account identifier string is empty.

Other = 4_294_967_295

Catch-all error variant reserved for forward-compatible mapping.

Implementations

impl Error

pub const fn code(&self) -> ErrorCode

Returns stable machine-readable error code.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

Returns 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.

impl From<AccountIdError> for Error

fn from(error: AccountIdError) -> Self

Converts to this type from the input type.

impl From<AssetError> for Error

fn from(error: AssetError) -> Self

Converts to this type from the input type.

impl Hash for Error

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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.
