Struct FraiseqlFunction 

pub struct FraiseqlFunction { /* private fields */ }

Auto-generated bindings for an instance a component which implements the world fraiseql-function.

This structure can be created through a number of means depending on your requirements and what you have on hand:

• The most convenient way is to use FraiseqlFunction::instantiate which only needs a Store, Component, and Linker.

• Alternatively you can create a FraiseqlFunctionPre ahead of time with a Component to front-load string lookups of exports once instead of per-instantiation. This method then uses FraiseqlFunctionPre::instantiate to create a FraiseqlFunction.

• If you’ve instantiated the instance yourself already then you can use FraiseqlFunction::new.

These methods are all equivalent to one another and move around the tradeoff of what work is performed when.

Implementations

impl FraiseqlFunction

pub fn instantiate<_T>( store: impl AsContextMut<Data = _T>, component: &Component, linker: &Linker<_T>, ) -> Result<FraiseqlFunction>

Convenience wrapper around FraiseqlFunctionPre::new and FraiseqlFunctionPre::instantiate.

pub fn new( store: impl AsContextMut, instance: &Instance, ) -> Result<FraiseqlFunction>

Convenience wrapper around FraiseqlFunctionIndices::new and FraiseqlFunctionIndices::load.

pub async fn instantiate_async<_T>( store: impl AsContextMut<Data = _T>, component: &Component, linker: &Linker<_T>, ) -> Result<FraiseqlFunction>

where _T: Send,

Convenience wrapper around FraiseqlFunctionPre::new and FraiseqlFunctionPre::instantiate_async.

pub fn add_to_linker<T, D>( linker: &mut Linker<T>, host_getter: fn(&mut T) -> D::Data<'_>, ) -> Result<()>

where D: HostWithStore<T> + HostWithStore<T> + HostWithStore<T> + Send, for<'a> D::Data<'a>: Host + Host + Host + Send, T: 'static + Send,

pub fn func_handle(&self) -> TypedFunc<(&str,), (Result<String, String>,)>

pub fn call_handle<S: AsContextMut>( &self, store: S, arg0: &str, ) -> Result<Result<String, String>>
