Enum TxGateError 

pub enum TxGateError {
    Parse(ParseError),
    PolicyDenied {
        rule: String,
        reason: String,
    },
    Sign(SignError),
    Store(StoreError),
    Config(ConfigError),
    Policy(PolicyError),
}

Top-level error type for the TxGate signing service.

This enum wraps all domain-specific error types and provides automatic conversion via the #[from] attribute.

Variants

Parse(ParseError)

Transaction parsing failed.

PolicyDenied

Policy denied the transaction.

Fields

rule: String

The policy rule that denied the request.

reason: String

Human-readable reason for denial.

Sign(SignError)

Signing operation failed.

Store(StoreError)

Key storage operation failed.

Config(ConfigError)

Configuration error.

Policy(PolicyError)

Policy evaluation error (not denial, but evaluation failure).

Implementations

impl TxGateError

pub fn policy_denied(rule: impl Into<String>, reason: impl Into<String>) -> Self

Create a policy denied error.

Trait Implementations

impl Debug for TxGateError

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

Formats the value using the given formatter.

impl Display for TxGateError

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

Formats the value using the given formatter.

impl Error for TxGateError

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.
