Central error type for all seer-core operations.

Marked #[non_exhaustive] so adding a variant is not a semver break for downstream consumers (matches need a wildcard arm). Third-party error types (reqwest, hickory) are converted to owned data at the From boundary instead of being embedded, so a major bump of those dependencies no longer changes this public API.

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.

WhoisError(String)

WhoisServerNotFound(String)

WhoisConnectionFailed(String)

RdapError(String)

RdapBootstrapError(String)

DnsError(String)

DnsResolverError(String)

Low-level resolver transport failure, captured as text at the From<hickory_resolver::net::NetError> boundary.

InvalidDomain(String)

DomainNotAllowed

Fields

domain: String

tld: String

InvalidIpAddress(String)

InvalidRecordType(String)

HttpError(String)

ReqwestError

Transport-level HTTP failure, captured as owned data at the From<reqwest::Error> boundary.

Fields

message: String

Upstream error text (reqwest’s Display), kept for logging.

transient: bool

Whether the failure is transient (connect / timeout / 429 / 5xx), classified once while the typed error is still available. Read by the retry classifier (crate::retry::NetworkRetryClassifier).

JsonError(Error)

Timeout(String)

RateLimited(String)

CertificateError(String)

SslError(String)

BulkOperationError

Fields

context: String

failures: Vec<(String, String)>

LookupFailed

Fields

domain: String

details: String

registry_url: String

ConfigError(String)

InvalidInput(String)

Other(String)

RetryExhausted

Fields

attempts: usize

last_error: Box<SeerError>

Implementations

impl SeerError

pub fn sanitized_message(&self) -> String

Returns a sanitized error message safe for external exposure (API responses, MCP tool results, Python exceptions).

Transport/network variants collapse to their CATEGORY with no inner detail, so an upstream server hostname/URL, a resolver-config fragment, a filesystem path, or a raw system error can never reach an external consumer. Full detail is still available for internal logging via the Display impl (to_string()) — log that, return this. User-input echoes (invalid domain / IP / record type / not-allowed TLD / generic input validation) are kept because they are the caller’s own input and are needed to act on the error.

Trait Implementations

impl Debug for SeerError

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

Formats the value using the given formatter.

impl Display for SeerError

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

Formats the value using the given formatter.

impl Error for SeerError

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<Error> for SeerError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for SeerError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<NetError> for SeerError

fn from(e: NetError) -> Self

Converts to this type from the input type.
