Struct rdftk_iri::Query

pub struct Query(_);

This type holds the query component of the IRI. While it is common in URLs to see queries of the form key=value&key=value... this is not part of the specification which explicitly makes the format of queries opaque:

The query component is a string of information to be interpreted by the resource.

Example

use rdftk_iri::Query;
use std::str::FromStr;

let query = Query::from_str("page1").unwrap();
println!("'{}'", query); // prints '?page1'

let query = Query::from_str("page=1&size=20").unwrap();
println!("'{}'", query); // prints '?page=1&size=20'

Implementations

impl Query

pub fn is_empty(&self) -> bool

Return true if the path is the empty string "" (which is a legal value), else false.

pub fn value(&self) -> &String

Return the current value of this fragment as a String.

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl Default for Query

fn default() -> Self

Returns the “default value” for a type.

impl Display for Query

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

Formats the value using the given formatter.

impl FromStr for Query

type Err = IriError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Query

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Normalize for Query

fn normalize(self) -> IriResult<Self>

Return a normalized version of self. The default for normalization is to do nothing and return self unchanged.

impl Ord for Query

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<Query> for Query

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

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

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

This method tests for !=.

impl PartialOrd<Query> for Query

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

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

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

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

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

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

impl PercentEncoding for Query

fn encode(&self, for_uri: bool) -> Self where
    Self: Sized, 

Construct a new value that has been percent encoded. If for_uri is true this method will also encode all non-ascii characters as a sequence of UTF-8 octets in percent encoded form.

impl ValidateStr for Query

fn is_valid(s: &str) -> bool

Return true if the string is a valid representation of Self, else false.

impl Eq for Query

impl StructuralEq for Query

impl StructuralPartialEq for Query
