The error kind for errors that get returned in the crate

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.

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

Character data length exceeded the limit

Fields

max: usize

Specified maximum

len: usize

Actual length

LabelOverlapsWithOther

Overlapping labels

Fields

label: usize

Start of the label that is overlaps

other: usize

Start of the other label

Nsec

Available on crate feature dnssec only.

No Records and there is a corresponding DNSSEC Proof for NSEC

Fields

query: Box<Query>

Query for which the NSEC was returned

proof: Proof

DNSSEC proof of the record

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

Format error in Message Parsing

Fields

header: Header

Header of the bad Message

error: Box<ProtoError>

Error that occured while parsing the Message

HmacInvalid()

An HMAC failed to verify

IncorrectRDataLengthRead

The length of rdata read was not as expected

Fields

read: usize

The amount of read data

len: usize

The expected length of the data

LabelBytesTooLong(usize)

Label bytes exceeded the limit of 63

PointerNotPriorToLabel

Label bytes exceeded the limit of 63

Fields

idx: usize

index of the label containing this pointer

ptr: u16

location to which the pointer is directing

MaxBufferSizeExceeded(usize)

The maximum buffer size was exceeded

MaxRecordLimitExceeded

Maximum record limit was exceeded

Fields

count: usize

number of records

record_type: RecordType

The record type that triggered the error.

Message(&'static str)

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

Msg(String)

An error with an arbitrary message, stored as String

NoConnections

No resolvers available

NoError

No error was specified

NotAllRecordsWritten

Not all records were able to be written

Fields

count: usize

Number of records that were written before the error

NoRecordsFound

No records were found for a query

Fields

query: Box<Query>

The query for which no records were found.

soa: Option<Box<Record<SOA>>>

If an SOA is present, then this is an authoritative response or a referral to another nameserver, see the negative_type field.

ns: Option<Arc<[ForwardNSData]>>

Nameservers may be present in addition to or in lieu of an SOA for a referral The tuple struct layout is vec[(Nameserver, [vec of glue records])]

negative_ttl: Option<u32>

negative ttl, as determined from DnsResponse::negative_ttl this will only be present if the SOA was also present.

response_code: ResponseCode

ResponseCode, if NXDOMAIN, the domain does not exist (and no other types). If NoError, then the domain exists but there exist either other types at the same label, or subzones of that label.

trusted: bool

If we trust NXDOMAIN errors from this server

authorities: Option<Arc<[Record]>>

Authority records from the query. These are important to preserve for DNSSEC validation.

UnknownAlgorithmTypeValue(u8)

An unknown algorithm type was found

An unknown dns class was found

UnknownDnsClassValue(u16)

An unknown dns class value was found

UnknownRecordTypeStr(String)
