Implementations§

Returns the sugared return type for an async function.

For example, if the return type is impl std::future::Future<Output = i32>, this function will return i32.

Panics

This function will panic if the return type does not match the expected sugaring for async functions.

  • header_len: The length of the function header and name. In other words, the number of characters in the function declaration up to but not including the parentheses.
    Used to determine line-wrapping.
  • indent: The number of spaces to indent each successive line with, if line-wrapping is necessary.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
