Enum PlacementFailure 

#[non_exhaustive]
pub enum PlacementFailure {
    Unsupported,
    OutOfRange,
    Os {
        code: i32,
    },
}

Why a worker could not be confined to a logical processor.

Every variant leaves the thread with the affinity it had before the attempt.

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.

Unsupported

This target has no thread-binding backend.

OutOfRange

The processor id is beyond what the target affinity interface can name.

Os

The operating system refused the request, for example because the processor is offline or outside the allowed set of the process.

Fields

code: i32

Raw operating-system error code: GetLastError on Windows, errno on Linux.

impl Eq for PlacementFailure

impl Error for PlacementFailure

Available on crate feature std only.

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
