[−][src]Struct tera::Context
The struct that holds the context of a template rendering.
Light wrapper around a BTreeMap
for easier insertions of Serializable
values
Implementations
impl Context
[src]
pub fn new() -> Self
[src]
Initializes an empty context
pub fn insert<T: Serialize + ?Sized, S: Into<String>>(
&mut self,
key: S,
val: &T
)
[src]
&mut self,
key: S,
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.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.
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);
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
