Struct mdns_sd::TxtProperties

pub struct TxtProperties { /* private fields */ }

Represents properties in a TXT record.

The key string of a property is case insensitive, and only one TxtProperty is stored for the same key.

RFC 6763: “A given key SHOULD NOT appear more than once in a TXT record.”

Implementations

impl TxtProperties

pub fn iter(&self) -> impl Iterator<Item = &TxtProperty>

Returns an iterator for all properties.

pub fn len(&self) -> usize

Returns the number of properties.

pub fn is_empty(&self) -> bool

Returns if the properties are empty.

pub fn get(&self, key: &str) -> Option<&TxtProperty>

Returns a property for a given key, where key is case insensitive.

pub fn get_property_val(&self, key: &str) -> Option<Option<&[u8]>>

Returns a property value for a given key, where key is case insensitive.

Returns None if key does not exist. Returns Some(Option<&u8>) for its value.

pub fn get_property_val_str(&self, key: &str) -> Option<&str>

Returns a property value string for a given key, where key is case insensitive.

Returns None if key does not exist. Returns Some("") if its value is None or is empty.

Trait Implementations

impl Clone for TxtProperties

fn clone(&self) -> TxtProperties

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TxtProperties

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

Formats the value using the given formatter.

impl Display for TxtProperties

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

Formats the value using the given formatter.

impl PartialEq for TxtProperties

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
