Struct ContextBuilder

pub struct ContextBuilder { /* private fields */ }

A builder for Context.

Create with Context::builder.

Implementations

impl ContextBuilder

pub fn new() -> Self

pub fn memory_limit(self, max_bytes: usize) -> Self

Sets the memory limit of the Javascript runtime (in bytes).

If the limit is exceeded, methods like eval will return a Err(ExecutionError::Exception(JsValue::Null))

pub fn console<B>(self, backend: B) -> Self

where B: ConsoleBackend,

Set a console handler that will proxy console.{log,trace,debug,...} calls.

The given argument must implement the console::ConsoleBackend trait.

A very simple logger could look like this:

pub fn build(self) -> Result<Context, ContextError>

Finalize the builder and build a JS Context.
