Struct PluginPolicy 

pub struct PluginPolicy {
    pub framework: FrameworkId,
    pub allow_official: bool,
    pub allow_user: bool,
    pub require_digest: bool,
}

Host policy for selecting which linked plugin manifests may participate. 宿主选择已链接插件是否参与的策略。

Fields

framework: FrameworkId

Framework whose manifests this policy governs. 本策略所管辖 manifest 的目标框架。

allow_official: bool

Whether official-sourced manifests may be selected. 是否允许选中官方来源的 manifest。

allow_user: bool

Whether user-sourced manifests may be selected. 是否允许选中用户来源的 manifest。

require_digest: bool

Reject manifests whose checksum is not a cryptographic digest. 拒绝不是密码学摘要的插件 manifest。

Implementations

impl PluginPolicy

pub const fn local(framework: FrameworkId) -> PluginPolicy

Deny every source; for hosts that link no external plugin. 拒绝所有来源；供不链接外部插件的宿主使用。

pub const fn open(framework: FrameworkId) -> PluginPolicy

Admit both official and user sources without a digest requirement. 同时接受官方与用户来源，且不要求密码学摘要。

pub const fn strict(framework: FrameworkId) -> PluginPolicy

Open policy with cryptographic checksum enforcement enabled. 开放来源但强制校验密码学摘要的策略。

pub fn accepts( self, plugin: PluginManifest, catalog: Option<&PluginCatalog>, ) -> bool

Whether the manifest is admitted, collapsing the reason to a boolean. 该 manifest 是否被接纳；原因被折叠成一个布尔值。

catalog is the host’s official lock record. Pass it whenever the host has one: an official manifest is only compared against the lock when a catalog is supplied, so None skips that check. The predicate takes the catalog rather than assuming it away because the old form hardcoded None, which made PluginRejectReason::LockMismatch unreachable for every caller — a self-declared Official manifest was admitted on its own word. catalog 是宿主的官方锁记录；宿主手上有它就应当传入：只有提供目录时，官方 manifest 才会 与锁记录比对，None 会跳过该检查。本谓词把目录作为参数、而不是假称它不存在，因为旧写法 硬编码 None，使 PluginRejectReason::LockMismatch 对每个调用方都不可达——一个自称 Official 的 manifest 仅凭自述就被接纳。

pub fn decision( self, plugin: PluginManifest, catalog: Option<&PluginCatalog>, ) -> PluginDecision

Explain selection instead of silently dropping a linked plugin. 返回筛选原因，不再让已链接插件静默消失。
