PacRuntimeBuilder

rama::js::pac

Struct PacRuntimeBuilder 

pub struct PacRuntimeBuilder { /* private fields */ }
Available on crate features js and pac and std only.
Expand description

A PAC environment bound to exactly one javascript runtime.

Unlike JsRuntimeBuilder, this builder is deliberately not cloneable: its host functions share one evaluation budget and cache, so reusing the bound blueprint for another runtime would make those runtimes interfere. Clone the PacEnv and call PacEnv::register again instead.

Implementations§

§

impl PacRuntimeBuilder

pub fn build(self) -> Result<(JsRuntime, PacBudgetHandle), JsError>

Build the bound runtime on the current thread and return its budget handle, which the caller arms before each evaluation.

pub fn spawn(self) -> Result<(JsWorker, PacBudgetHandle), JsError>

Spawn the bound runtime on a worker with the default configuration.

pub fn spawn_with( self, worker: JsWorkerBuilder, ) -> Result<(JsWorker, PacBudgetHandle), JsError>

Spawn the bound runtime using worker and return its budget handle.
