Module std::runtime::internal

Functions

• fn coroutine_new<Func, Args, YieldT, RecvT>(args: Args) -> Coroutine<YieldT, RecvT>

  Func: NamedFunction

  Args: Tuple

  source

  Glue code for creating a generator.

  Calls to this function are generated by the compiler when a generator function is called. Not meant to be called directly.

• fn coroutine_yield<YieldT, RecvT>(val: &YieldT, out: &mut RecvT) -> bool

  source

  Implementation of the yield keyword.

  It is not recommended to call this function directly, use the yield keyword instead, but it can be used to yield from a function that is not a generator, but has a generator in its call stack.

  Returns true if the generator was cancelled and false otherwise.

  Calling this function outside of a generator or yielding a different type than the generator expects is undefined behavior.

• fn entrypoint<UserMain>(argc: c_int, argv: &&c_char) -> c_int

  UserMain: NamedFunction

  source

  Program entrypoint glue.

  This is equivalent to C's main, not _start as we still want to use the C runtime for invoking the static constructors.

  It converts the argc and argv arguments to a slice of strings, initializes the main thread associated data (if threading is enabled) and then invokes the user-defined main function.

Macros

Consts

• const STACK_ARGS_MAX: usize = /* ... */

  source

  Maximum number of program arguments that can be stack-allocated.

  See allocate_args for details.
