WalObjectReservationKey

krabka_remote_storage::diskless::index

Struct WalObjectReservationKey 

Source 
pub struct WalObjectReservationKey { /* private fields */ }
Expand description

Object UUID encoded into the existing delete-floor key space.

Diskless object names use UUIDv4. Changing only the version nibble to v8 creates a reversible namespace that cannot collide with generated diskless topic IDs, while the negative partition sentinel keeps the record inert to older delete-floor projections.

Implementations§

Source§

impl WalObjectReservationKey

Source

pub fn new(object_id: Uuid) -> Self

Source

pub fn object_id(self) -> Uuid

Source

pub fn to_bytes(self) -> Bytes

Source

pub fn from_bytes(bytes: &[u8]) -> Option<Self>

Source

pub const fn key_version() -> i16

This record deliberately shares the v1 delete-floor key/value versions, so persisted 1.x readers can still replay it.

§

fn fg(&self, value: Color) -> Painted<&T>

This method should be used rarely. Instead, prefer to use color-specific builder methods like red() and green(), which have the same functionality but are pithier.

§Example

Set foreground color to white using fg():

use yansi::{Paint, Color};

painted.fg(Color::White);

Set foreground color to white using white().

use yansi::Paint;

painted.white();

§

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

Enables the yansi [Quirk] value.
