Struct PidFileContents 

pub struct PidFileContents {
    pub pid: i32,
    pub started_at_secs: i64,
}

Parsed pidfile contents. Format on disk is three newline-terminated lines:

<pid>
heddle-agent
<start_time_unix_secs>

The marker line lets agent stop reject a pidfile that wasn’t written by us. Combined with the process-identity check in is_heddle_process, this closes the “PID got reused after a dirty crash” hole that the reviewer flagged: even if <pid> now belongs to some unrelated process, we won’t SIGTERM it.

Fields

pid: i32

started_at_secs: i64

Implementations

impl PidFileContents

pub fn render(&self) -> String

Render the file body. Always trailing-newline so cat round-trips.

pub fn parse(body: &str) -> Option<Self>

Parse a pidfile body. Returns None when the file isn’t in the heddle format — the caller should treat this as “not a heddle pidfile” and refuse to act on it.

Trait Implementations

impl Clone for PidFileContents

fn clone(&self) -> PidFileContents

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PidFileContents

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

Formats the value using the given formatter.

impl PartialEq for PidFileContents

fn eq(&self, other: &PidFileContents) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
