[−][src]Struct sapper_std::WebContext
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]
pub fn new() -> Context
[src]
Initializes an empty context
pub fn insert<T>(&mut self, key: &str, val: &T) where
T: Serialize + ?Sized,
[src]
T: Serialize + ?Sized,
Converts the val
parameter to Value
and insert it into the context
ⓘThis example is not tested
let mut context = Context::new(); // user is an instance of a struct implementing `Serialize` context.insert("number_users", 42);
pub fn extend(&mut self, source: Context)
[src]
Appends the data of the source
parameter to self
, overwriting existing keys.
The source context will be dropped.
ⓘThis example is not tested
let mut target = Context::new(); target.insert("a", 1); target.insert("b", 2); let mut source = Context::new(); source.insert("b", 3); source.insert("d", 4); target.extend(source);
