Errors returned by Chainlink event 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.

WrongTopic

The log did not contain the expected event signature topic.

Fields

expected: B256

Expected topic0.

actual: Option<B256>

Actual topic0, if present.

WrongTopicCount

The log had the wrong number of topics.

Fields

expected: usize

Expected topic count.

actual: usize

Actual topic count.

WrongDataLength

The data payload had the wrong byte length.

Fields

expected: usize

Expected byte length.

actual: usize

Actual byte length.

Uint64Overflow

A uint256 event field did not fit into the crate’s typed Rust field.

Fields

field: &'static str

Field name.

value: U256

Encoded value.

AbiDecode

ABI decoding failed for a dynamic or typed event payload.

Fields

event: &'static str

Event name.

message: String

Decoder error message.

Trait Implementations

impl Eq for ChainlinkEventDecodeError

impl Error for ChainlinkEventDecodeError

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
