Enum heim::process::ProcessError

#[non_exhaustive]pub enum ProcessError {
    NoSuchProcess(i32),
    ZombieProcess(i32),
    AccessDenied(i32),
    Load(Error),
}

This is supported on crate feature process only.

Error which might happen during the process information fetching.

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.

NoSuchProcess(i32)

Process with this pid does not exists.

ZombieProcess(i32)

Might be returned when querying zombie process on Unix systems.

AccessDenied(i32)

Not enough permissions to query the process information.

Load(Error)

Data loading failure.
