Struct ContextSnapshot 

#[non_exhaustive]
pub struct ContextSnapshot {
    pub message_count: usize,
    pub message_metas: Vec<MessageMeta>,
    pub has_system: bool,
    pub operator_id: OperatorId,
    pub estimated_tokens: usize,
}

Read-only snapshot of an OperatorContext for introspection and logging.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

message_count: usize

Number of messages currently in the context.

message_metas: Vec<MessageMeta>

Metadata for each message, in order.

has_system: bool

Whether a system prompt is currently set.

operator_id: OperatorId

The operator this context belongs to.

estimated_tokens: usize

Rough token estimate derived from the debug representation length of messages.

Uses the heuristic total_chars / 4. Not suitable for billing — use it for soft pressure signals only.
