rust-uritemplate is a Rust implementation of
RFC6570 - URI Template that can process
URI Templates up to and including ones designated as Level 4 by the
specification. It passes all of the tests in the
uritemplate-test test
suite.
Variable setting can be chained for nice, clean code.
let uri = UriTemplate::new("/view/{object:1}/{/object,names}{?query*}")
.set("object", "lakes")
.set("names", &["Erie", "Superior", "Ontario"])
.set("query", &[("size", "15"), ("lang", "en")])
.build();
assert_eq!(uri, "/view/l/lakes/Erie,Superior,Ontario?size=15&lang=en");It is not possible to set a variable to the value "undefined". Instead, simply delete the variable if you have already set it.
let mut t = UriTemplate::new("{hello}");
t.set("hello", "Hello World!");
assert_eq!(t.build(), "Hello%20World%21");
t.delete("hello");
assert_eq!(t.build(), "");The delete function returns true if the variable existed and false
otherwise.
Any type that implements IntoTemplateVar can be set as the value of a
UriTemplate variable. The following implementations are provided by default
for each type of variable:
- Scalar Values:
String,&str - Lists:
Vec<String>,&[String],&[str] - Associative Arrays:
Vec<(String, String)>,&[(String, String)],&[(&str, &str)],&HashMap<String, String>
In addition, you can implement IntoTemplateVar for your own types. View the
documentation for IntoTemplateVar for information on how that works.
