Struct QueryRef 

pub struct QueryRef<'a> { /* private fields */ }

Available on crate feature net only.

Borrowed view of a URI query component (no leading ?).

Implementations

impl<'a> QueryRef<'a>

pub fn as_bytes(&self) -> &'a [u8]

Returns the raw bytes.

pub fn as_raw_str(&self) -> &'a str

Returns the raw query as &str (no percent-decoding). UTF-8 by parser invariant.

pub fn as_decoded_str(&self) -> Cow<'a, str>

Percent-decoded query string. Cow::Borrowed when no %XX escapes are present; Cow::Owned otherwise. UTF-8 errors fall back to U+FFFD.

pub fn into_owned(self) -> Query

Returns an owned copy. Named into_owned (matching std::borrow::Cow::into_owned) so it doesn’t shadow the std ToOwned trait method.

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

Iterator over name[=value] pairs.

Follows WHATWG URLSearchParams / form-urlencoded splitting: & delimits pairs, the first = in each pair delimits name from value, empty fragments (&&, leading/trailing &) are dropped. Each QueryPair keeps the bare-vs-empty-value distinction — ?foo → value = None, ?foo= → value = Some("").

pub fn deserialize<T>(&self) -> Result<T, QueryDeserializeError>

where T: Deserialize<'a>,

Deserialize the query into T with application/x-www-form-urlencoded semantics: + → space, %XX → byte, repeated keys collect into a Vec<_> field.

Bare keys (?foo) decode as foo="", matching WHATWG URLSearchParams. This diverges from pairs which keeps the bare-vs-empty distinction — use that iterator if you need it.

Fields can borrow from the query bytes: &'a str and Cow<'a, str> skip the allocation when the source value has no + / %XX to decode. When decoding is needed, &'a str fails (the decoded bytes don’t live in the input) while Cow<'a, str> falls back to Cow::Owned. Prefer Cow<'a, str> or String for fields that may contain escapes.

Trait Implementations

impl<'a> Clone for QueryRef<'a>

fn clone(&self) -> QueryRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for QueryRef<'a>

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

Formats the value using the given formatter.

impl Display for QueryRef<'_>

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

Renders the query bytes (no leading ?). Raw on-wire form — pct-encoding is preserved as-is.

impl<'a> Hash for QueryRef<'a>

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

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for QueryRef<'a>

fn cmp(&self, other: &QueryRef<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for QueryRef<'a>

fn eq(&self, other: &QueryRef<'a>) -> 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.

impl<'a> PartialOrd for QueryRef<'a>

fn partial_cmp(&self, other: &QueryRef<'a>) -> 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.
