Enum Error 

#[non_exhaustive]
pub enum Error {
    Boundary,
    HeaderTooLong,
    TooManyHeaders,
    Header,
    UnexpectedEof,
    Disposition,
}

Every failure the crate can report. See DESIGN.md §12.

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.

Boundary

The boundary is not 1–70 RFC 2046 bchars ending in a non-space byte, the Content-Type carries no usable boundary parameter, or a boundary_from_random array has an invalid size (rule 1).

HeaderTooLong

A part header line (including its CRLF) is longer than LINE (rule 5.1).

TooManyHeaders

A part has more than MAX_HEADERS header lines (rule 5.4).

Header

A header line is malformed: bare LF, missing colon, empty or non-token name, obs-fold, CR inside the line (rule 5); or an encoder content type containing CR/LF (§11).

UnexpectedEof

The input ended before the close delimiter (rule 7).

Disposition

A Content-Disposition value does not follow RFC 2183 syntax (rule 8).

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

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 Eq for Error

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<E> From<Error> for ReadError<E>

fn from(e: Error) -> Self

Converts to this type from the input type.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
