Enum FormError 

pub enum FormError {
    InvalidContentType,
    BodyReadError(String),
    InvalidUtf8,
    ParseError(String),
    DeserializationError(String),
}

Error type for Form extraction.

Represents various failure modes that can occur when extracting and parsing form data from HTTP request bodies. This error type implements std::error::Error for integration with error handling libraries.

Variants

InvalidContentType

Request content type is not application/x-www-form-urlencoded.

BodyReadError(String)

Failed to read the request body.

InvalidUtf8

Request body contains invalid UTF-8 sequences.

ParseError(String)

Failed to parse the form data format.

DeserializationError(String)

Failed to deserialize form data into the target type.

Trait Implementations

impl Clone for FormError

fn clone(&self) -> FormError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FormError

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

Formats the value using the given formatter.

impl Display for FormError

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

Formats the value using the given formatter.

impl Eq for FormError

impl Error for FormError

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 PartialEq for FormError

fn eq(&self, other: &FormError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Responder for FormError

fn into_response(self) -> Response<TakoBody>

Converts the error into an HTTP response.

Maps form extraction errors to appropriate HTTP status codes with descriptive error messages. All errors result in 400 Bad Request as they indicate client-side issues with the request format or content.

Examples

use tako::extractors::form::FormError;
use tako::responder::Responder;
use http::StatusCode;

let error = FormError::InvalidContentType;
let response = error.into_response();
assert_eq!(response.status(), StatusCode::BAD_REQUEST);

let error = FormError::InvalidUtf8;
let response = error.into_response();
assert_eq!(response.status(), StatusCode::BAD_REQUEST);
