Enum DecodingKind 

pub enum DecodingKind {
    InvalidEncoding,
    OutOfRange,
    Overflow,
    InvalidTag,
    Missing,
    Trailing,
    Unsupported,
}

Which fault a decoder found in the data it refused, so a responder can name it (#1446). DecodingKind::reject_reason gives the Clause 18.9 Reject reason each kind draws when the data was a confirmed request.

Variants

InvalidEncoding

Contents whose encoding isn’t valid for their datatype: a wrong length, an Unsigned of no octets or with padding a canonical field refuses, an unknown character set, a BIT STRING’s unused-bit count past 7, and the like. The kind Error::decoding makes.

OutOfRange

A value too large for its field’s width, or outside the range the production or service gives it.

Overflow

More than the decoder takes: a count of items past its limit, or a tag length past its sanity bound.

InvalidTag

A tag that doesn’t fit where it stands: another number, class or form than the member there needs, a closing tag that closes no open frame, a tag header that is itself malformed, or an opening tag nested deeper than the decoder walks.

Missing

The data ends, or the enclosing frame closes, where a required member or a frame’s closing tag is due: a member is missing.

Trailing

Octets are left after the last member of a value that must fill its input: arguments beyond those the production has.

Unsupported

A well-formed encoding the decoder doesn’t handle: a CharacterString in a character set it can’t convert (IBM/Microsoft DBCS, JIS X 0208 or UCS-4).

Implementations

impl DecodingKind

pub fn reject_reason(self) -> RejectReason

Overflow	BUFFER_OVERFLOW
InvalidTag	INVALID_TAG
Missing	MISSING_REQUIRED_PARAMETER
Trailing	TOO_MANY_ARGUMENTS
Unsupported	OTHER
