The struct that holds the context of a template rendering.
Light wrapper around a BTreeMap
for easier insertions of Serializable
values
Methods
impl Context
[src]
fn new() -> Context
Initializes an empty context
fn add<T: Serialize>(&mut self, key: &str, val: &T)
Converts the val
parameter to Value
and insert it into the context
let mut context = Context::new(); // user is an instance of a struct implementing `Serialize` context.add("number_users", 42);
fn extend(&mut self, source: Context)
Appends the data of the source
parameter to self
overwriting existing keys.
The source context will be dropped
let mut target = Context::new(); target.add("a", 1); target.add("b", 2); let mut source = Context::new(); source.add("b", 3); source.add("d", 4); target.extend(source);
