Struct BriefContext 

pub struct BriefContext {
    pub turn: u64,
    pub goal: Option<String>,
    pub user_message: Option<String>,
    pub budget: TokenBudget,
    pub now: SystemTime,
}

Per-turn input handed to every crate::source::Source.

Sources read from ctx to decide what to contribute. turn, goal, and user_message are caller-supplied; budget is informational here (enforcement is the builder’s job); now lets sources timestamp without reaching for the clock directly, which keeps tests deterministic.

Fields

turn: u64

Turn number within the current session. Monotonically increasing.

goal: Option<String>

Optional running goal carried across turns.

user_message: Option<String>

The user’s latest message, if any.

budget: TokenBudget

Token budget for this turn.

now: SystemTime

Wall-clock time the builder considers “now”. Sources should prefer this over SystemTime::now() so tests are reproducible.

Implementations

impl BriefContext

pub fn new(budget: TokenBudget) -> Self

Construct a BriefContext with the supplied budget and now = SystemTime::now(). The remaining optional fields default to None / 0.

pub fn with_turn(self, turn: u64) -> Self

Set the turn number.

pub fn with_goal(self, goal: impl Into<String>) -> Self

Set the running goal.

pub fn with_user_message(self, message: impl Into<String>) -> Self

Set the user message.

pub fn with_now(self, now: SystemTime) -> Self

Override now (used in tests for deterministic time).

Trait Implementations

impl Clone for BriefContext

fn clone(&self) -> BriefContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BriefContext

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BriefContext

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BriefContext

fn eq(&self, other: &BriefContext) -> 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 BriefContext

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
