Struct Query 

pub struct Query(/* private fields */);

Percent-encoded URL query, without the leading ?.

Implementations

impl Query

pub const fn as_str(&self) -> &str

Returns the component as a string slice.

impl Query

pub fn new(src: &str) -> Result<&Query, InvalidUrl>

Strictly validates a query: *( pchar / "/" / "?" ).

pub fn is_empty(&self) -> bool

Returns true if the query is empty.

pub fn decode(&self) -> Cow<'_, str>

Returns the decoded query. + is decoded as space; escapes of &, =, + and ; are kept.

pub fn pairs(&self) -> QueryPairs<'_>

Returns an iterator over decoded key=value pairs.

use urly::Url;

let url = Url::from_static("/?a=1&b=x+y&a=%32&flag");
let pairs: Vec<_> = url.query().unwrap().pairs().collect();
let pairs: Vec<_> = pairs.iter().map(|(k, v)| (&**k, &**v)).collect();
assert_eq!(pairs, [("a", "1"), ("b", "x y"), ("a", "2"), ("flag", "")]);

pub fn get<'a>(&'a self, key: &str) -> Option<Cow<'a, str>>

Returns the first decoded value for key.

use urly::Url;

let url = Url::from_static("/?a=1&a=2&b=%C3%BC");
let query = url.query().unwrap();
assert_eq!(query.get("a").unwrap(), "1");
assert_eq!(query.get("b").unwrap(), "ü");
assert_eq!(query.get_all("a").collect::<Vec<_>>(), ["1", "2"]);
assert!(!query.contains_key("c"));

pub fn get_all<'a>(&'a self, key: &str) -> impl Iterator<Item = Cow<'a, str>>

Returns all decoded values for key.

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

Returns true if the query contains key.

Trait Implementations

impl AsRef<str> for Query

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for Query

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

Formats the value using the given formatter.

impl Display for Query

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

Formats the value using the given formatter.

impl Eq for Query

impl Hash for Query

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

impl Ord for Query

fn cmp(&self, other: &Query) -> Ordering

This method returns an Ordering between self and other.

impl PartialEq for Query

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

Equality operator ==.

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

Inequality operator !=.

impl PartialEq<&str> for Query

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

Equality operator ==.

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

Inequality operator !=.

impl PartialEq<Query> for str

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

Equality operator ==.

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

Inequality operator !=.

impl PartialEq<Query> for &str

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

Inequality operator !=.

impl PartialEq<str> for Query

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Query

fn partial_cmp(&self, other: &Query) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> TryFrom<&'a str> for &'a Query

type Error = InvalidUrl

The type returned in the event of a conversion error.

fn try_from(s: &'a str) -> Result<Self, Self::Error>

Performs the conversion.
