Struct Scope 

pub struct Scope {
    pub org_id: String,
    pub agent_id: Option<String>,
    pub user_id: Option<String>,
    pub session_id: Option<String>,
}

Hierarchical scope for memory isolation.

The minimum required field is org_id. All other fields are optional and progressively narrow the scope. A Scope with only org_id is an “org-level” scope; adding user_id narrows it to a user; adding session_id narrows it further to a single conversation session.

agent_id is orthogonal — it tracks which agent instance wrote or owns a piece of memory, without affecting the containment hierarchy.

Fields

org_id: String

Organisation (tenant) identifier. Required; defaults to "default".

agent_id: Option<String>

Agent instance identifier (optional).

user_id: Option<String>

End-user identifier (optional).

session_id: Option<String>

Conversation session identifier (optional).

Implementations

impl Scope

pub fn org(org_id: impl Into<String>) -> Self

Org-level scope — broadest.

pub fn user(org_id: impl Into<String>, user_id: impl Into<String>) -> Self

User-level scope — scoped to a specific end-user within an org.

pub fn session( org_id: impl Into<String>, user_id: impl Into<String>, session_id: impl Into<String>, ) -> Self

Session-level scope — scoped to a single conversation session.

pub fn full( org_id: impl Into<String>, agent_id: impl Into<String>, user_id: impl Into<String>, session_id: impl Into<String>, ) -> Self

Full scope — all four fields set.

pub fn depth(&self) -> u8

Scope depth: 0 = org-only, 1 = +user, 2 = +session, 3 = all four fields.

agent_id alone does not increase depth; depth measures the narrowing along the org → user → session hierarchy.

pub fn contains(&self, other: &Scope) -> bool

Returns true if self is a parent (or equal) scope of other.

A scope contains another when:

• Both belong to the same org.
• Every field set in self matches the corresponding field in other. Fields absent in self are wildcards.

Trait Implementations

impl Clone for Scope

fn clone(&self) -> Scope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scope

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

Formats the value using the given formatter.

impl Default for Scope

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Scope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Scope

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 PartialEq for Scope

fn eq(&self, other: &Scope) -> 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 Serialize for Scope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Scope

impl StructuralPartialEq for Scope
