Struct CopyOwner 

pub struct CopyOwner {
    pub pid: i64,
    pub birth_identity: String,
    pub pid_namespace: Option<String>,
}

What: The process identity that owns an item: the process id, the identity of its birth, and its process-id namespace. Why: A process id alone is reused; the birth identity tells a reused id from the owner, and the namespace tells an owner this process cannot interpret from one that is gone.

In TS you’d write (pseudocode):

type CopyOwner = { pid: number; birthIdentity: string; pidNamespace?: string };

Fields

pid: i64

The owner’s process id.

birth_identity: String

The owner’s birth identity as the platform reports it.

pid_namespace: Option<String>

The owner’s process-id namespace, when the platform has one.

Implementations

impl CopyOwner

pub fn token(&self) -> String

The owner as text that holds no dot, slash, space or other character a file name’s parts cannot carry, in about forty characters for a Linux process.

pub fn from_token(token: &str) -> Option<CopyOwner>

The owner a token names, or nothing when the text is no token (a name an older release wrote, or a stranger’s).

pub fn is_alive(&self, item: &Path) -> Result<bool, WorktreeCopyError>

What: Whether the owner still runs. Why: An owner in a PID namespace this process cannot see is judged by how recently its item changed (item’s age), because its process id means nothing here; any other owner is alive when a process with its id and its birth exists.

In TS you’d write (pseudocode):

owner.isAlive(itemPath);

Errors

When the platform refuses to report the process.
