The error kind for errors that get returned in the crate

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.

BadQueryCount(usize)

Query count is not one

Busy

The underlying resource is too busy

This is a signal that an internal resource is too busy. The intended action should be tried again, ideally after waiting for a little while for the situation to improve. Alternatively, the action could be tried on another resource (for example, in a name server pool).

Canceled(Canceled)

An error caused by a canceled future

CharacterDataTooLong

Fields

max: usize

Specified maximum

len: usize

Actual length

Character data length exceeded the limit

LabelOverlapsWithOther

Fields

label: usize

Start of the label that is overlaps

other: usize

Start of the other label

Overlapping labels

DnsKeyProtocolNot3(u8)

DNS protocol version doesn’t have the expected version 3

DomainNameTooLong(usize)

A domain name was too long

EdnsNameNotRoot(Name)

EDNS resource record label is not the root label, although required

FormError

Fields

header: Header

Header of the bad Message

error: Box<ProtoError>

Error that occured while parsing the Message

Format error in Message Parsing

HmacInvalid()

An HMAC failed to verify

IncorrectRDataLengthRead

Fields

read: usize

The amount of read data

len: usize

The expected length of the data

The length of rdata read was not as expected

LabelBytesTooLong(usize)

Label bytes exceeded the limit of 63

PointerNotPriorToLabel

Fields

idx: usize

index of the label containing this pointer

ptr: u16

location to which the pointer is directing

Label bytes exceeded the limit of 63

MaxBufferSizeExceeded(usize)

The maximum buffer size was exceeded

Message(&'static str)

An error with an arbitrary message, referenced as &’static str

Msg(String)

An error with an arbitrary message, stored as String

NoError

No error was specified

NotAllRecordsWritten

Fields

count: usize

Number of records that were written before the error

Not all records were able to be written

RrsigsNotPresent

Fields

name: Name

The record set name

record_type: RecordType

The record type

Missing rrsigs
