Struct InstanceBuilder

Source 
pub struct InstanceBuilder<'a> { /* private fields */ }
Expand description

A builder for instances; created by Region::new_instance_builder().

Implementations§

Source§

impl<'a> InstanceBuilder<'a>

Source

pub fn with_embed_ctx<T: Any>(self, ctx: T) -> Self

Add an embedder context to the built instance.

Up to one context value of any particular type may exist in the instance. If a context value of the same type already exists, it is replaced by the new value.

Source

pub fn build(self) -> Result<InstanceHandle, Error>

Build the instance.

§Safety

This function runs the guest code for the WebAssembly start section, and running any guest code is potentially unsafe; see Instance::run().
