Constructors

• .new(name : String, lib_path : String, handle : Pointer(Void), source_code : String = "")

Instance Method Summary

• #async(return_type : T.class, func_name : String, *args) : Future(T) forall T

  Asynchronously executes the C kernel function on a background fiber without blocking the caller

• #call(func_name : String, *args) : Int64

  Calls an exported symbol dynamically, defaulting to Int64 return

• #call_as(return_type : T.class, func_name : String, *args) : T forall T

  Calls an exported symbol with explicit return type

• #call_with_callback(func_name : String, *args, &block : Int64, Int64 -> Nil) : Nil

  Calls a C function passing a Crystal callback closure and its context

• #close
• #disassemble(func_name : String | Nil = nil) : String

  Radare2 machine code disassembly inspection

• #export_to_ruby(ruby_class_or_mod : String, ruby_method_name : String, c_func_name : String, param_types : Array(String) = [] of String, return_type : String = "Int64") : Nil

  Exports a function from this kernel directly into embedded CRuby as a singleton method

• #function(func_name : String, return_type : String = "Int64") : NativeFunction

  Returns a callable NativeFunction handle for a specific exported symbol

• #handle : Pointer(Void)
• #lib_path : String
• #name : String
• #pipe(input_channel : Channel(U), output_type : V.class, func_name : String, *args, capacity : Int32 = 64) : Channel(V) forall U, V

  Connects an input channel to a C processing kernel that streams to an output channel

• #source_code : String
• #stream(item_type : T.class, func_name : String, *args, capacity : Int32 = 64) : Channel(T) forall T

  Streams real-time data from a C kernel into a Crystal Channel(T)
