Enum Error 

pub enum Error {
    Auth(String),
    Validation {
        code: String,
        message: String,
    },
    RateLimited {
        retry_after: Duration,
    },
    Server(String),
    Network(Error),
    Decode(Error),
}

Unified error surface for typed-client operations.

Variants

Auth(String)

Authentication or authorization failure (HTTP 401/403, bad header bytes, etc.). Caller should re-credential, not retry the same payload.

Validation

Server rejected the request payload or current state (HTTP 4xx other than 401/403/429). code is the TaskFast error envelope tag (e.g. "validation_error"); message is the human-readable detail.

Fields

code: String

TaskFast components/schemas/Error.error short code.

message: String

Human-readable detail from the API response body.

RateLimited

Server responded 429 Too Many Requests. retry_after reflects the Retry-After header (or a 1-second default when absent/unparseable).

Fields

retry_after: Duration

Duration callers should sleep before re-issuing the request.

Server(String)

Server-side failure (HTTP 5xx) or pre-flight client-side error that callers should treat as transient + retry-eligible.

Network(Error)

Underlying transport (DNS, connect, TLS, body stream) failed.

Decode(Error)

Response body could not be deserialised into the expected schema.

Implementations

impl Error

pub fn kind(&self) -> &'static str

Short, stable variant tag for logging without leaking the inner message. A compromised server (or an endpoint that echoes request bodies into its error strings) could land an X-API-Key value inside an Auth/Server payload — logging the full Display would then page the secret into any log sink. Callers that need logging should prefer Self::kind over ?err.

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(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
