Implementations§

source§

impl<T> Linker<T>

source

pub fn new(engine: &Engine) -> Self

source

pub fn func_fallback( &mut self, func: impl Fn(Caller<'_, T>, &[u8]) -> Result<(), Trap> + Send + Sync + 'static, )

Defines a fallback external call handler, in case no other registered functions match.

source

pub fn func_new( &mut self, symbol: impl AsRef<[u8]>, func: impl Fn(Caller<'_, T>) -> Result<(), Trap> + Send + Sync + 'static, ) -> Result<&mut Self, Error>
where T: 'static,

Defines a new dynamically typed handler for external calls with a given symbol.

source

pub fn func_wrap<Params, Args>( &mut self, symbol: impl AsRef<[u8]>, func: impl IntoCallFn<T, Params, Args>, ) -> Result<&mut Self, Error>

Defines a new statically typed handler for external calls with a given symbol.

source

pub fn instantiate_pre(&self, module: &Module) -> Result<InstancePre<T>, Error>

Pre-instantiates a new module, linking it with the external functions previously defined on this object.
