Struct QueryParams 

pub struct QueryParams { /* private fields */ }

Query parameters parsed from URL query string

Supports multiple values for the same key.

Example

use gpui_navigator::QueryParams;

let query = QueryParams::from_query_string("page=1&sort=name&tag=rust&tag=gpui");

assert_eq!(query.get("page"), Some(&"1".to_string()));
assert_eq!(query.get_as::<i32>("page"), Some(1));
assert_eq!(query.get_all("tag").unwrap().len(), 2);

Implementations

impl QueryParams

pub fn new() -> Self

Create empty query parameters.

pub fn from_query_string(query: &str) -> Self

Parse from query string

Example

use gpui_navigator::QueryParams;

let query = QueryParams::from_query_string("page=1&sort=name");
assert_eq!(query.get("page"), Some(&"1".to_string()));

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

Get the first value for a key.

pub fn get_all(&self, key: &str) -> Option<&Vec<String>>

Get all values for a key.

Useful for parameters that can appear multiple times (e.g. ?tag=rust&tag=gpui).

pub fn get_as<T>(&self, key: &str) -> Option<T>

where T: FromStr,

Get the first value for a key, parsed as type T.

Returns None if the key is missing or the value cannot be parsed.

pub fn insert(&mut self, key: impl Into<String>, value: impl Into<String>)

Append a value for the given key.

If the key already exists, the new value is added to the list (not replaced).

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

Return true if the given key is present.

pub fn to_query_string(&self) -> String

Serialize back into a query string.

Example

use gpui_navigator::QueryParams;

let mut query = QueryParams::new();
query.insert("page".to_string(), "1".to_string());
let s = query.to_query_string();
assert!(s.contains("page=1"));

pub fn is_empty(&self) -> bool

Return true if there are no parameters.

pub fn len(&self) -> usize

Return the number of unique parameter keys.

Trait Implementations

impl Clone for QueryParams

fn clone(&self) -> QueryParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryParams

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

Formats the value using the given formatter.

impl Default for QueryParams

fn default() -> QueryParams

Returns the “default value” for a type.

impl Eq for QueryParams

impl PartialEq for QueryParams

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