Struct tera::Context [−][src]
pub struct Context { /* fields omitted */ }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]
impl Contextpub fn new() -> Context[src]
pub fn new() -> ContextInitializes an empty context
pub fn insert<T: Serialize + ?Sized>(&mut self, key: &str, val: &T)[src]
pub fn insert<T: Serialize + ?Sized>(&mut self, key: &str, val: &T)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]
pub fn extend(&mut self, source: Context)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);
