Struct ToolHistoryPolicy 

pub struct ToolHistoryPolicy {
    pub dedup_arg: Option<&'static str>,
    pub summary_arg: Option<&'static str>,
    pub compactable_result: bool,
    pub pins_active_plan: bool,
}

Tool-authored context-retention hints for history transforms.

The core loop does not interpret these policies directly. They are narrow metadata for ContextTransform plugins that need to summarize or trim history without maintaining a parallel list of tool names.

Fields

dedup_arg: Option<&'static str>

Argument whose string value identifies duplicate calls of the same tool. Older successful results for the same value may be replaced by a marker that points at the latest result.

summary_arg: Option<&'static str>

Argument to render in compact one-line summaries.

compactable_result: bool

Whether old successful results are re-fetchable enough to clear during time-based microcompaction.

pins_active_plan: bool

Whether the latest successful result should be pinned near the newest user turn as the active plan.

Implementations

impl ToolHistoryPolicy

pub const fn new() -> Self

pub const fn dedup_arg(self, arg: &'static str) -> Self

pub const fn summary_arg(self, arg: &'static str) -> Self

pub const fn compactable_result(self) -> Self

pub const fn pins_active_plan(self) -> Self

Trait Implementations

impl Clone for ToolHistoryPolicy

fn clone(&self) -> ToolHistoryPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolHistoryPolicy

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

Formats the value using the given formatter.

impl Default for ToolHistoryPolicy

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ToolHistoryPolicy

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