[−][src]Trait uritemplate::IntoTemplateVar
IntoTemplateVar represents any type that can be converted into a TemplateVar
for use as the value of a template variable, such as a String,
Vec<String>, or Vec<(String, String)>. Default implementations are
available for those three types, as well as the &str versions.
Example
Here is an example of implementing IntoTemplateVar for your own Address
struct. Note that you should probably implement the trait for a reference to
your struct, not the actual struct, unless you intend to move the value
efficiently.
ⓘThis example is not tested
struct Address { city: String, state: String } impl <'a> IntoTemplateVar for &'a Address { fn into_template_var(self) -> TemplateVar { TemplateVar::AssociativeArray(vec![ ("city".to_string(), self.city.clone()), ("state".to_string(), self.state.clone()) ]) } }
Now, Address variables can be set as UriTemplate variables.

let address = Address { city: "Los Angelos".to_string(), state: "California".to_string() }; let uri = UriTemplate::new("http://example.com/view{?address*}") .set("address", &address) .build(); assert_eq!( uri, "http://example.com/view?city=Los%20Angelos&state=California" );
