Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidProcessId(u32),
    SomethingWentWrong,
    NotSupported,
    PermissionDenied,
    PlatformSpecificError(PlatformError),
}

Represents errors that can occur in the library.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidProcessId(u32)

The process ID is invalid for observing windows.

Platform-specific

• Windows: This occurs when the process ID is zero.
• macOS: This does not occur on macOS.

SomethingWentWrong

This occurs when the application is not ready yet. This also occurs when the application that has given PID is not found.

Platform-specific

• Windows: This does not occur on windows.

NotSupported

The application does not support observing window events.

Platform-specific

• Windows: This does not occur on windows.

PermissionDenied

Permission denied error. This error only occurs on macOS.

PlatformSpecificError(PlatformError)

A platform-specific error occurred.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<WindowsError> for Error

fn from(source: PlatformError) -> Self

Converts to this type from the input type.
