Struct Properties

pub struct Properties { /* private fields */ }

Properties type (key-value pairs)

Implementations

impl Properties

pub fn new() -> Properties

Create an instance

pub fn len(&self) -> usize

Get the number of the properties

pub fn is_empty(&self) -> bool

Check if properties has 0 elements

pub fn iter(&self) -> impl DoubleEndedIterator<Item = (&str, &str)>

Get an iterator of the properties

pub fn contains_key<S: AsRef<str>>(&self, s: S) -> bool

Return true if property exist

pub fn insert<K, V>(&mut self, k: K, v: V)

where K: Into<String>, V: Into<String>,

Insert (key, value) pair by replace

pub fn append<K, V>(&mut self, k: K, v: V)

where K: Into<String>, V: Into<String>,

Append key with (key, value) pair

pub fn get<S: AsRef<str>>(&self, s: S) -> Option<&str>

Get the first value associate with the key

pub fn get_all<S: AsRef<str>>( &self, s: S, ) -> impl DoubleEndedIterator<Item = &str>

Get all values associate with the key

pub fn remove<S: AsRef<str>>(&mut self, s: S) -> Option<String>

Remove the property with the first value of the key

pub fn remove_all<S: AsRef<str>>( &mut self, s: S, ) -> impl DoubleEndedIterator<Item = String> + '_

Remove the property with all values with the same key

Trait Implementations

impl Clone for Properties

fn clone(&self) -> Properties

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Properties

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

Formats the value using the given formatter.

impl Default for Properties

fn default() -> Properties

Returns the “default value” for a type.

impl<S: AsRef<str>> Index<S> for Properties

type Output = str

The returned type after indexing.

fn index(&self, index: S) -> &str

Performs the indexing (container[index]) operation.

impl PartialEq for Properties

fn eq(&self, other: &Properties) -> 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.
