§Constructing

An ErrorKind can be constructed directly or via a From of the following types:

Variants (Non-exhaustive)§

This enum is marked as 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.
§

InvalidLength

Fields

§min: Option<u64>

The minimum length required, inclusive.

§max: Option<u64>

The maximum length required, inclusive.

The value’s length, in bytes, was outside the range [min, max].

§

InvalidChoice

Fields

§choices: Cow<'v, [Cow<'v, str>]>

The choices that were expected.

The value wasn’t one of the valid choices.

§

OutOfRange

Fields

§start: Option<isize>

The start of the acceptable range, inclusive.

§end: Option<isize>

The end of the acceptable range, inclusive.

The integer value was outside the range [start, end].

§

Validation(Cow<'v, str>)

A custom validation routine failed with message .0.

§

Duplicate

One entity was expected but more than one was received.

§

Missing

An entity was expected but was not received.

§

Unexpected

An unexpected entity was received.

§

Unknown

An unknown entity was received.

§

Custom(Status, Box<dyn Error + Send>)

A custom error occurred. Status defaults to Status::UnprocessableEntity if one is not directly specified.

§

Multipart(Error)

An error while parsing a multipart form occurred.

§

Utf8(Utf8Error)

A string was invalid UTF-8.

§

Int(ParseIntError)

A value failed to parse as an integer.

§

Bool(ParseBoolError)

A value failed to parse as a boolean.

§

Float(ParseFloatError)

A value failed to parse as a float.

§

Addr(AddrParseError)

A value failed to parse as an IP or socket address.

§

Io(Error)

An I/O error occurred.
