Detailed Description

Representation of a function in Wasmtime.

Functions in Wasmtime are represented as an index into a store and don't have any data or destructor associated with the wasmtime_func_t value. Functions cannot interoperate between wasmtime_store_t instances and if the wrong function is passed to the wrong store then it may trigger an assertion to abort the process.
