Enum FaucetError 

pub enum FaucetError {
    Http(Error),
    HttpStatus {
        status: u16,
        url: String,
        body: String,
    },
    Json(Error),
    JsonPath(String),
    Auth(String),
    RateLimited(Duration),
    Url(String),
    Transform(String),
    Config(String),
    Source(String),
    Sink(String),
    Custom(Box<dyn Error + Sync + Send>),
}

All possible errors returned by faucet-stream.

Variants

Http(Error)

HttpStatus

An HTTP response with a non-success status code.

Contains the status code, URL, and (truncated) response body for debugging. Whether this error is retriable depends on the status code — see FaucetError::is_retriable.

Fields

status: u16

url: String

body: String

Json(Error)

JsonPath(String)

Auth(String)

RateLimited(Duration)

The server responded with HTTP 429 Too Many Requests. The inner value is the duration to wait before retrying, parsed from the Retry-After response header (default: 60 s).

Url(String)

A URL could not be constructed or parsed.

Transform(String)

A record transform could not be compiled or applied (e.g. invalid regex).

Config(String)

A configuration or validation error (e.g. invalid endpoint, missing descriptor).

Source(String)

A source operation failed (e.g. database query error, file read error).

Sink(String)

A sink operation failed (e.g. BigQuery insert error).

Custom(Box<dyn Error + Sync + Send>)

A custom error from a third-party connector.

Use this to wrap your own error types without losing the error chain:

use faucet_core::FaucetError;
let err = FaucetError::Custom(Box::new(std::io::Error::new(
    std::io::ErrorKind::Other,
    "my connector failed",
)));

Implementations

impl FaucetError

pub fn is_retriable(&self) -> bool

Whether this error is transient and the request should be retried.

Retriable errors:

• Network / connection errors (Http from reqwest)
• Server errors (5xx status codes)
• Rate limiting (429 — handled separately with Retry-After)

Non-retriable errors:

• Client errors (4xx except 429)
• JSON parse / JSONPath / auth / transform errors

Trait Implementations

impl Debug for FaucetError

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

Formats the value using the given formatter.

impl Display for FaucetError

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

Formats the value using the given formatter.

impl Error for FaucetError

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.
