Enum Error 

#[non_exhaustive]
pub enum Error {
    DuplicateHeader(HeaderName),
    EmptyAuth,
    Forbidden {
        message: String,
    },
    BasicAuthWithHttp,

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.

DuplicateHeader(HeaderName)

EmptyAuth

Forbidden

Fields

message: String

BasicAuthWithHttp

HttpError(Box<Error>)

HttpNotOk(StatusCode, String)

Query(Box<QueryError>)

A query failed on the Trino coordinator. Match on the inner QueryError’s error_code / error_name / error_type to react to a specific failure; the full structured error is also reachable through std::error::Error::source.

Decode(String)

Failed to decode or deserialize a response or a spooled segment.

Tls(String)

Failed to load or read a TLS certificate.

Protocol(String)

The server used a protocol the client cannot handle in this context (e.g. mixing the Direct and Spooled protocols across pages, or spooled data received without the spooling feature enabled).

Transaction(String)

A transaction operation was attempted in a state that does not allow it — starting a transaction while one is already active, or committing or rolling back without one.

OAuth2(String)

The interactive OAuth2 authentication flow failed (no token server in the challenge, the token endpoint returned an error, or it timed out).

InconsistentData

ReachMaxAttempt(usize)

InvalidHost(String)

InternalError(String)

An unexpected, internal failure that callers are not expected to handle.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<QueryError> for Error

fn from(err: QueryError) -> Self

Converts to this type from the input type.
