Enum ContractError 

#[non_exhaustive]
pub enum ContractError {
    InvalidAbi {
        message: String,
    },
    InvalidAddress {
        address: String,
        reason: String,
    },
    EncodingError {
        message: String,
    },
    DecodingError {
        message: String,
    },
}

Errors that can occur during contract ABI encoding/decoding.

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.

InvalidAbi

Invalid ABI type or value.

Fields

message: String

Description of the ABI validation failure.

InvalidAddress

Invalid address format.

Fields

address: String

The address string that failed validation.

reason: String

Why the address is invalid.

EncodingError

Encoding failure.

Fields

message: String

Description of the encoding failure.

DecodingError

Decoding failure.

Fields

message: String

Description of the decoding failure.

Trait Implementations

impl Clone for ContractError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractError

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

Formats the value using the given formatter.

impl Display for ContractError

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

Formats the value using the given formatter.

impl Error for ContractError

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<AbiDecodeError> for ContractError

fn from(err: AbiDecodeError) -> Self

Converts to this type from the input type.

impl From<ContractError> for ProviderError

fn from(err: ContractError) -> Self

Converts to this type from the input type.
