A set of errors that can occur during parsing multipart stream and in other operations.

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.

UnknownField

Fields

field_name: Option<String>

An unknown field is detected when multipart constraints are added.

IncompleteFieldData

Fields

field_name: Option<String>

The field data is found incomplete.

IncompleteHeaders

Couldn’t read the field headers completely.

ReadHeaderFailed(Error)

Failed to read headers.

DecodeHeaderName

Fields

name: String

cause: Box<dyn Error + Send + Sync>

Failed to decode the field’s raw header name to HeaderName type.

DecodeHeaderValue

Fields

value: Vec<u8>

cause: Box<dyn Error + Send + Sync>

Failed to decode the field’s raw header value to HeaderValue type.

IncompleteStream

Multipart stream is incomplete.

FieldSizeExceeded

Fields

limit: u64

field_name: Option<String>

The incoming field size exceeded the maximum limit.

StreamSizeExceeded

Fields

limit: u64

The incoming stream size exceeded the maximum limit.

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

Stream read failed.

LockFailure

Failed to lock the multipart shared state for any changes.

NoMultipart

The Content-Type header is not multipart/form-data.

DecodeContentType(FromStrError)

Failed to convert the Content-Type to mime::Mime type.

NoBoundary

No boundary found in Content-Type header.

DecodeJson(Error)

Available on crate feature json only.

Failed to decode the field data as JSON in field.json() method.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl PartialEq<Error> for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
