uri_encode

URI percent-encoding for Rust, providing functions equivalent to JavaScript's encodeURI() and encodeURIComponent().

Installation

[dependencies]
uri_encode = "1.0"

Usage

use uri_encode::{encode_uri, encode_uri_component, encode_query_param};

// Encode a complete URL (preserves structure)
let url = encode_uri("https://example.com/path?q=hello world");
assert_eq!(url, "https://example.com/path?q=hello%20world");

// Encode a URL component (more aggressive)
let component = encode_uri_component("path/with spaces");
assert_eq!(component, "path%2fwith%20spaces");

// Encode query parameters (spaces become +)
let param = encode_query_param("hello world");
assert_eq!(param, "hello+world");

Functions

encode_uri

Encodes a complete URI while preserving its structure. Equivalent to JavaScript's encodeURI().

Preserves: A-Z a-z 0-9 - _ . ! ~ * ' ( ) ; , / ? : @ & = + $ #

encode_uri("https://example.com/hello world?name=foo bar")
// => "https://example.com/hello%20world?name=foo%20bar"

encode_uri_component

Encodes a URI component such as a path segment or query value. Equivalent to JavaScript's encodeURIComponent().

Preserves: A-Z a-z 0-9 - _ . ! ~ * ' ( )

encode_uri_component("hello world&foo=bar")
// => "hello%20world%26foo%3dbar"

encode_query_param

Encodes a query parameter using application/x-www-form-urlencoded format. Spaces become +.

encode_query_param("John Doe")
// => "John+Doe"
