Struct wasmedge_sdk::Instance
source · pub struct Instance { /* private fields */ }Expand description
Represents an instantiated module.
An Instance represents an instantiated module. In the instantiation process, A module instance is created based on a compiled module. From a [module instance] the exported host function, table, memory, and global instances can be fetched.
Implementations§

sourcepub fn func_names(&self) -> Option<Vec<String>>
pub fn func_names(&self) -> Option<Vec<String>>
Returns the names of the exported function instances in this module instance.
sourcepub fn func(&self, name: impl AsRef<str>) -> WasmEdgeResult<Func>
pub fn func(&self, name: impl AsRef<str>) -> WasmEdgeResult<Func>
Returns the exported function instance in this module instance by the given function name.
Argument
name- the name of the target exported function instance.
sourcepub fn global_count(&self) -> usize
