Enum ClientError 

#[non_exhaustive]
pub enum ClientError {
    Builder(String),
    Http(Error),
    Decode(Error),
    ProtocolError {
        code: u16,
        msg: String,
    },
    Signature(String),
    SignatureMismatch {
        expected: String,
        recovered: String,
    },
    InvalidKey(String),
    WebSocket(String),
    Validation(String),
}

The single error type returned by every fallible operation in this SDK.

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.

Builder(String)

Client setup failure (bad URL, TLS init, etc.).

Http(Error)

HTTP transport failure (connection refused, timeout, etc.).

Decode(Error)

JSON encode / decode failure.

ProtocolError

The server returned an error envelope with a code + message.

code is the HTTP status code; msg is the error field from the MTF-native error envelope ({"error": "..."}).

Fields

code: u16

HTTP status code returned by the server.

msg: String

Error message from the server’s error envelope.

Signature(String)

EIP-712 signature production failed.

SignatureMismatch

The signature recovered does not match the wallet’s address.

This indicates an internal bug — the SDK signed a message but recovering the signer from the digest + signature did not yield the expected address. Should never happen in practice.

Fields

expected: String

Expected signer address (hex, no 0x prefix).

recovered: String

Recovered signer address (hex, no 0x prefix).

InvalidKey(String)

Private key parsing failed (wrong length / not hex / out of curve).

WebSocket(String)

WebSocket transport failure.

Validation(String)

User input failed local validation before any network call.

Trait Implementations

impl Debug for ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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.
