[][src]Struct tera::Context

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]

Initializes an empty context

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);

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);
