Struct UriTemplate

pub struct UriTemplate { /* private fields */ }

The main struct that processes and builds URI Templates.

Implementations

impl UriTemplate

pub fn new(template: &str) -> UriTemplate

Creates a new URI Template from the given template string.

Example

let t = UriTemplate::new("http://example.com/{name}");

pub fn set<I: IntoTemplateVar>( &mut self, varname: &str, var: I, ) -> &mut UriTemplate

Sets the value of a variable in the URI Template.

Example

let mut t = UriTemplate::new("{name}");
t.set("name", "John Smith");

This function returns the URITemplate so that the set() calls can be chained before building.

let uri = UriTemplate::new("{firstname}/{lastname}")
    .set("firstname", "John")
    .set("lastname", "Smith")
    .build();
assert_eq!(uri, "John/Smith");

pub fn delete(&mut self, varname: &str) -> bool

Deletes the value of a variable in the URI Template. Returns true if the variable existed and false otherwise.

Example

let mut t = UriTemplate::new("{animal}");
t.set("animal", "dog");
assert_eq!(t.delete("house"), false);
assert_eq!(t.delete("animal"), true);

pub fn delete_all(&mut self)

Deletes the values of all variables currently set in the URITemplate.

pub fn build(&self) -> String

Expands the template using the set variable values and returns the final String.

Example

let mut t = UriTemplate::new("{hello}");
t.set("hello", "Hello World!");
assert_eq!(t.build(), "Hello%20World%21");
