Struct boa_engine::context::ContextBuilder

pub struct ContextBuilder { /* private fields */ }

Builder for the Context type.

This builder allows custom initialization of the Interner within the context.

Implementations

impl ContextBuilder

pub fn new() -> Self

Creates a new ContextBuilder with a default empty Interner and a default BoaProvider if the intl feature is enabled.

pub fn interner(self, interner: Interner) -> Self

Initializes the context Interner to the provided interner.

This is useful when you want to initialize an Interner with a collection of words before parsing.

pub fn host_hooks<H: HostHooks + 'static>(self, host_hooks: &'static H) -> Self

Initializes the HostHooks for the context.

pub fn job_queue<Q: JobQueue + 'static>(self, job_queue: Rc<Q>) -> Self

Initializes the JobQueue for the context.

pub fn module_loader<M: ModuleLoader + 'static>( self, module_loader: Rc<M> ) -> Self

Initializes the ModuleLoader for the context.

pub const fn can_block(self, can_block: bool) -> Self

AgentCanSuspend ( ) aka [[CanBlock]]

Defines if this context can be suspended by calls to the Atomics.wait function.

Note

By the specification, multiple agents cannot share the same thread if any of them has its [[CanBlock]] field set to true. The builder will verify at build time that all contexts on the current thread fulfill this requisite.

pub fn build(self) -> JsResult<Context>

Builds a new Context with the provided parameters, and defaults all missing parameters to their default values.
