Struct Context 

pub struct Context { /* private fields */ }

The variables a single render can see.

Not to be confused with rustlavel_core::Context, which is the application’s long-lived typed state. This one is per-render, cheap, and intentionally untyped: a view is the one place where the shape of the data is decided by whoever is editing the HTML.

use rustlavel_core::Json;
use rustlavel_view::Context;

let context = Context::new()
    .with("title", "Dashboard")
    .with("user", Json::object([("name", Json::from("Ada"))]));

assert_eq!(context.get("title").unwrap(), &Json::from("Dashboard"));

Implementations

impl Context

pub fn new() -> Self

pub fn with(self, key: impl Into<String>, value: impl Into<Json>) -> Self

Add a variable, chaining: Context::new().with("user", user).

pub fn insert(&mut self, key: impl Into<String>, value: impl Into<Json>)

Add a variable to an existing context.

pub fn get(&self, key: &str) -> Option<&Json>

pub fn from_json(value: Json) -> Self

Turn a JSON object into a context, so a handler that already built one does not have to take it apart again. Anything else yields an empty context — a template’s top level is a set of named variables.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl PartialEq for Context

fn eq(&self, other: &Context) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
