Struct ControlTokenGuard 

pub struct ControlTokenGuard { /* private fields */ }

One session’s control token file, written for exactly as long as the session runs.

A guard of its own rather than part of RunningGuard: the token is written before the record, and a session whose record could not be written still runs and still holds a token.

Implementations

impl ControlTokenGuard

pub fn write(session_id: &str, token: &str) -> Result<Self, String>

Writes token to control_token_path at owner-only mode and holds it until this guard drops.

The Err names the path and why; it never carries the token.

Trait Implementations

impl Drop for ControlTokenGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
