impl Tags

source

pub fn new(map: BTreeMap<String, String>) -> Tags

source

pub fn empty() -> Tags

source

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

source

pub fn get_result(&self, k: &str) -> Result<&String>

source

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

source

pub fn has_any(&self, keys: Vec<&str>) -> bool

source

pub fn is(&self, k: &str, v: &str) -> bool

source

pub fn is_any(&self, k: &str, values: Vec<&str>) -> bool

source

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

source

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

source

pub fn is_empty(&self) -> bool

source

pub fn inner(&self) -> &BTreeMap<String, String>

source

pub fn into_inner(self) -> BTreeMap<String, String>

source

pub fn diff(&self, other: &Tags) -> Vec<(String, String, String)>

Trait Implementations§

impl Clone for Tags

source§

fn clone(&self) -> Tags

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl Debug for Tags

source§

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

Formats the value using the given formatter. Read more
source§

impl<'de> Deserialize<'de> for Tags

source§

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer. Read more
source§

impl PartialEq for Tags

source§

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

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
source§

impl Serialize for Tags

source§

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer. Read more
