Trait ResultExt

    // Required methods
    fn from_win32() -> Result<()>;
    fn err_from_win32() -> Result<T>;
    fn from_checked_or_win32<F>(t: T, check: F) -> Result<T>

Required Methods

fn from_win32() -> Result<()>

Returns Ok(()), or Err, based on windows::core::Error::from_win32().

fn err_from_win32() -> Result<T>

Returns Err with windows::core::Error::from_win32().

fn from_checked_or_win32<F>(t: T, check: F) -> Result<T>

where F: FnOnce(&T) -> bool,

Passes a T through to an Ok value, if the check is successful, or otherwise returns Err with windows::core::Error::from_win32().

Can be used transitionally in new cases, until this crate might offer a more suitable solution.

fn from_checked_or_e_fail<F>(t: T, check: F) -> Result<T>

where F: FnOnce(&T) -> bool,

Passes a T through to an Ok value, if the check is successful, or otherwise returns Err with HRESULT E_FAIL.

To be used with functions that don’t offer an error code via GetLastError().

Can be used transitionally in new cases, until this crate might offer a more suitable solution.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
