Available on crate feature alloc only.

A TXT record mDNS cannot carry, or an advertisement that cannot be built.

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.

InvalidKey

A key that is empty, contains =, or is not printable ASCII.

Fields

service_type: String

The record’s service type.

key: String

The key.

StringTooLong

A key=value string over TXT_STRING_MAX bytes.

Fields

service_type: String

The record’s service type.

key: String

The key.

bytes: usize

The string’s length in bytes.

NoDeviceId

An identity with no device id.

InvalidDeviceId(String)

An empty device id, or one containing a comma.

NoRole

An identity with no role.

InvalidRole(String)

An empty role, or one containing a comma.

Missing(&'static str)

A required identity field left empty: manufacturer, model, serial_number or ebus_version.

InvalidHomieDomain(String)

A Homie domain that is not one topic level.

DuplicateBrokerType(BrokerType)

Two brokers of one type in one advertisement.

Trait Implementations

impl Clone for TxtError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TxtError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TxtError

Formats the value using the given formatter.

impl Eq for TxtError

impl Error for TxtError

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 PartialEq for TxtError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
