Enum IncumbentError 

#[non_exhaustive]
pub enum IncumbentError {
    NotIncumbent {
        pid: u32,
    },
    NoIdentity {
        pid: u32,
    },
    OwnProcess,
    Survived {
        pid: u32,
    },
    Io(Error),
}

Why the incumbent was not replaced. Nothing was signalled for NotIncumbent, NoIdentity and OwnProcess.

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.

NotIncumbent

The pid is alive but is not the recorded process (a recycled pid): never signalled.

Fields

pid: u32

NoIdentity

The record carries no process start time, so no signal may be sent; the incumbent was asked and did not stop within the grace.

Fields

pid: u32

OwnProcess

The record names this process.

Survived

The incumbent is still running after the forced stop.

Fields

pid: u32

Io(Error)

The OS refused a query or a signal.
