[][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


impl Context[src]

pub fn new() -> Self[src]

Initializes an empty context

pub fn insert<T: Serialize + ?Sized>(&mut self, key: &str, val: &T)[src]

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);

pub fn into_json(self) -> Value[src]

Converts the context to a serde_json::Value consuming the context

pub fn from_value(obj: Value) -> TeraResult<Self>[src]

Takes a serde-json Value and convert it into a Context with no overhead/cloning

pub fn from_serialize(value: impl Serialize) -> TeraResult<Self>[src]

Takes something that impl Serialize and create a context with it. Meant to be used if you have a hashmap or a struct and don't want to insert values one by one in the context
