Struct ShardKey 

pub struct ShardKey {
    pub manga_id: Option<i32>,
    pub episode_id: i32,
}

分片键

编辑器域以话数为分片单元；漫画 ID 仅作辅助归类。

Fields

manga_id: Option<i32>

漫画 ID（可选，用于跨话数归类与缓存对齐）

episode_id: i32

话数 ID（主分片键）

Implementations

impl ShardKey

pub fn from_episode(episode_id: i32) -> Self

由话数 ID 构造分片键

pub fn partition(&self, partitions: u32) -> u32

计算该分片键落在哪个 HASH 分区（0..partitions）。

仅用于诊断/未来多库路由；单库部署下 PostgreSQL 自动路由，无需调用。

Trait Implementations

impl Clone for ShardKey

fn clone(&self) -> ShardKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShardKey

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

Formats the value using the given formatter.

impl PartialEq for ShardKey

fn eq(&self, other: &ShardKey) -> 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.
