Struct Lease 

Source 
pub struct Lease {
    pub member: MemberId,
    pub token: FencingToken,
    pub granted_at: i64,
    pub deadline: i64,
}
Expand description

The member that holds a role now, and the time its claim ends.

The token is the authority. The broker fences a write that carries an older token, and no clock takes part in that check. The deadline is an anti-flap device. A standby waits for the deadline to pass before it challenges the holder, so a short pause does not move the role.

Fields§

§member: MemberId

The member that holds the role.

§token: FencingToken

The quorum-minted proof of the claim of the holder.

§granted_at: i64

The time the holder took the lease, in milliseconds since the Unix epoch.

§deadline: i64

The time the lease expires, in milliseconds since the Unix epoch.

use yansi::{Paint, Color};

painted.fg(Color::White);

Set foreground color to white using white().

§

fn quirk(&self, value: Quirk) -> Painted<&T>
