Struct rquickjs::Context

pub struct Context { /* fields omitted */ }

A single execution context with its own global variables and stack.

Can share objects with other contexts of the same runtime.

Methods

impl Context

pub fn base(runtime: &Runtime) -> Result<Self>

Creates a base context with only the required functions registered. If additional functions are required use Context::build or Contex::full.

pub fn full(runtime: &Runtime) -> Result<Self>

Creates a context with all standart available functions registered. If precise controll is required of wich functions are availble use Context::build

pub fn build(rt: &Runtime) -> ContextBuilder

Create a context builder for creating a context with a specific set of intrinsics

pub fn set_max_stack_size(&self, size: usize)

Set the maximum stack size for the local context stack

pub fn enable_big_num_ext(&self, enable: bool)

pub fn with<F, R>(&self, f: F) -> R where
    F: FnOnce(Ctx) -> R, 

A entry point for manipulating and using javascript objects and scripts. The api is structured this way to avoid repeated locking the runtime when ever any function is called. This way the runtime is locked once before executing the callback. Furthermore, this way it is impossible to use values from different runtimes in this context which would otherwise be undefined behaviour.

This is the only way to get a Ctx object.

Trait Implementations

impl Drop for Context

fn drop(&mut self)

Executes the destructor for this type.
