Enum RuleSource 

pub enum RuleSource {
    Policy,
    User,
    Project,
    Session,
    Default,
}

规则来源 — 5 层优先级，高优先级来源的决策不可被低优先级覆盖。

Policy (最高) → User → Project → Session → Default (最低)

设计参考

• Claude-Code: 7 种来源
• OpenCode: 无来源概念（flat ruleset）
• katu: 5 层，兼顾灵活性与简洁性

Examples

use katu_core::permission::RuleSource;

assert!(RuleSource::Policy.priority() > RuleSource::User.priority());
assert!(RuleSource::User.priority() > RuleSource::Project.priority());

Variants

Policy

管理员策略 — 最高优先级，不可被用户覆盖。

来自企业管理平台或 policySettings。

User

用户全局设置 — 用户级偏好。

来自 ~/.config/katu/settings.toml。

Project

项目设置 — 项目级偏好。

来自 .katu/settings.toml（版本控制中共享）。

Session

会话 / 运行时 — 本次运行中动态添加的规则。

来自用户 “always allow” 选择或命令行参数。

Default

默认规则 — 最低优先级，内置兜底。

Implementations

impl RuleSource

pub fn priority(&self) -> u8

返回此来源的优先级数值（越大越高）。

pub fn is_immutable(&self) -> bool

此来源的规则是否不可被低优先级来源覆盖。

Trait Implementations

impl Clone for RuleSource

fn clone(&self) -> RuleSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RuleSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RuleSource

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RuleSource

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RuleSource

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for RuleSource

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

impl PartialOrd for RuleSource

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for RuleSource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for RuleSource

impl Eq for RuleSource

impl StructuralPartialEq for RuleSource
