Struct PolicySet 

pub struct PolicySet {
    pub policies: Vec<ContextPolicy>,
}

A set of loaded policies.

Fields

policies: Vec<ContextPolicy>

Implementations

impl PolicySet

pub fn new() -> Self

pub fn defaults() -> Self

Built-in default policies that align with existing LeanCTX behavior.

pub fn security_defaults() -> Self

Open Engine safety defaults. These remain mechanism-level security policy.

pub fn attach_compat_defaults() -> Self

Frozen OSS Attach compatibility heuristics.

These preserve the supported Coding-Agent experience but are not the canonical Product policy surface and must not gain new lifecycle rules.

pub fn evaluate( &self, path: &str, seen_before: bool, token_count: usize, ) -> Vec<PolicyEvalResult>

Evaluate all policies against a path, returning applicable actions.

pub fn evaluate_full( &self, path: &str, seen_before: bool, token_count: usize, agent_id: Option<&str>, role: Option<&str>, content: Option<&str>, ) -> Vec<PolicyEvalResult>

Evaluate with full context including agent/role/content dimensions.

pub fn effective_state( &self, path: &str, current: ContextState, seen_before: bool, token_count: usize, ) -> ContextState

Determine the effective state for an item after policy evaluation.

Actions fold in order (the last match wins), except that a matching security-default Exclude always wins: no later Pin, Include or MarkOutdated re-admits a secret, key or credential file.

pub fn recommended_view( &self, path: &str, seen_before: bool, token_count: usize, ) -> Option<ViewKind>

Determine the recommended view for an item after policy evaluation.

pub fn load_project(project_root: &Path) -> Self

Load policies from a project’s .lean-ctx/policies.json file.

The security defaults always come first and cannot be removed or redefined by the project file: a project policy reusing one of their names is dropped.

pub fn load_project_sourced( project_root: &Path, ) -> Vec<(ContextPolicy, PolicySource)>

Self::load_project with where each policy comes from, in effect order: the security defaults, then the project file’s policies (or, without a readable project file, the built-in defaults).

pub fn save_project(&self, project_root: &Path) -> Result<(), String>

Save policies to a project’s .lean-ctx/policies.json file.

Trait Implementations

impl Clone for PolicySet

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicySet

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

Formats the value using the given formatter.

impl Default for PolicySet

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PolicySet

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for PolicySet

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
