Errors encountered during fetching an object. Mostly related to parsing.

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.

Parse(Error)

Arbitrary parsing error.

Fetch(Error)

Arbitrary fetching error.

Io(Error)

ExtraInputLeft

Data left after an [Inline] got parsed.

EndOfInput

EOF.

AddressOutOfBounds

Overran [PointInput]’s [Address] vector.

ResolutionMismatch

[Address::hash] doesn’t match what [Resolve] returned.

DataMismatch

[FullHash::full_hash] doesn’t match [Singular::hash].

DiscriminantOverflow

Discriminant out of range for an [Enum].

Zero

Unepxected zero for a non-zero value.

OutOfBounds

Value out of bounds for a certain type.

UnsupportedLength

Current architecture (32-bit) is unable to handle lengths of this size.

Utf8(FromUtf8Error)

Not UTF-8.

UnknownExtension

[Resolve::extension] (or related things) were unable to resolve the extension.

ExtensionType

Extension type didn’t match what we asked for. This might be turned into panic later.

Unimplemented

HashNotFound

Implementations

impl Error

pub fn parse(e: impl Into<Error>) -> Self

Construct Error::Parse from another error.

pub fn fetch(e: impl Into<Error>) -> Self

Construct Error::Fetch from another error.

pub fn io(e: impl Into<Error>) -> Self

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(value: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(source: FromUtf8Error) -> Self

Converts to this type from the input type.
