Interface for interacting with underlying mDNS implementation TXT record capabilities

Required methods

fn new() -> Self

Constructs a new TXT record

fn insert(&mut self, key: &str, value: &str) -> Result<()>

Inserts the specified value at the specified key.

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

Returns the value at the specified key or None if no such key exists.

This function returns an owned String because there are no guarantees that the implementation provides access to the underlying value pointer.

fn remove(&mut self, key: &str) -> Result<()>

Removes the value at the specified key. Returns Err if no such key exists.

fn contains_key(&self, key: &str) -> bool

Returns true if the TXT record contains the specified key.

fn len(&self) -> usize

Returns the amount of entries in the TXT record.

fn iter<'a>(&'a self) -> Box<dyn Iterator<Item = (String, String)> + 'a>

Returns a new iterator for iterating over the record as you would a HashMap.

fn keys<'a>(&'a self) -> Box<dyn Iterator<Item = String> + 'a>

Returns a new iterator over the records keys.

fn values<'a>(&'a self) -> Box<dyn Iterator<Item = String> + 'a>

Returns a new iterator over the records values.

Provided methods

fn is_empty(&self) -> bool

Returns true if there are no entries in the record.

fn to_map(&self) -> HashMap<String, String>

Returns a new HashMap with this record’s keys and values.
