Struct EngineBuilder

Source

pub struct EngineBuilder<T> { /* private fields */ }

Expand description

A builder interface for configuring a new Engine.

A new EngineBuilder can be obtained with Engine::builder.

Implementations§

Source §

impl<T> EngineBuilder<T>

Source

pub fn linker(&mut self) -> &mut Linker<T>

Returns a reference to the Linker for this Engine.

Source

pub fn epoch_tick_interval(&mut self, interval: Duration)

Sets the epoch tick internal for the built Engine.

This is used by Store::set_deadline to calculate the number of “ticks” for epoch interruption, and by the default epoch ticker thread. The default is DEFAULT_EPOCH_TICK_INTERVAL.

See EngineBuilder::epoch_ticker_thread and wasmtime::Config::epoch_interruption.

Source

pub fn epoch_ticker_thread(&mut self, enable: bool)

Configures whether the epoch ticker thread will be spawned when this Engine is built.

Enabled by default; if disabled, the user must arrange to call engine.as_ref().increment_epoch() every epoch_tick_interval or interrupt-based features like Store::set_deadline will not work.

Source

pub fn build(self) -> Engine<T>

Builds an Engine from this builder.
