Struct DynamicCatalogSnapshot 

Source
pub struct DynamicCatalogSnapshot {
    pub generation: u64,
    pub snapshot_digest: String,
    pub registry: DefinitionRegistry,
    pub definition_records: Vec<DefinitionRecord>,
    pub capabilities: Vec<RegisteredCapability>,
}
Expand description

业务作用:把同一数据库 generation 的 definition 与有效 capability 形成不可拆分加载结果。

Fields§

§generation: u64

本次读取确认的共享 generation。

§snapshot_digest: String

definition 与 route 内容形成的确定性摘要,供多副本确认同一代快照。

§registry: DefinitionRegistry

active 与仍被旧实例引用的 deprecated definition 快照。

§definition_records: Vec<DefinitionRecord>

当前 generation 中候选与可运行 definition 的完整持久化记录。

§capabilities: Vec<RegisteredCapability>

读取时仍在服务端租约内的参与方逐实例能力。

Implementations§

Source§

impl DynamicCatalogSnapshot

Source

pub fn new( generation: u64, registry: DefinitionRegistry, capabilities: Vec<RegisteredCapability>, ) -> Self

业务作用:把已复验的 definition 与 capability 组合为带确定性内容摘要的代际快照。

参数说明:generation 是共享代际,registry 是运行定义,capabilities 是有效路由。

返回:返回可供多副本确认的不可拆分快照。

Source

pub fn with_definition_records( generation: u64, registry: DefinitionRegistry, definition_records: Vec<DefinitionRecord>, capabilities: Vec<RegisteredCapability>, ) -> Self

业务作用:把 candidate、active、deprecated definition 与有效 capability 共同绑定进快照摘要。

参数说明:generation 是共享代际,registry 只承载可运行定义,definition_records 还包含 尚未激活的候选定义,capabilities 是读取时有效的逐实例路由。

返回:摘要覆盖租户、owner、生命周期、seal 和路由且字段边界无歧义的不可拆分快照。
