Struct TurnMetrics 

pub struct TurnMetrics {
    pub turn_index: usize,
    pub prev_total: u32,
    pub delta: u32,
    pub is_heavy: bool,
    pub is_active: bool,
    pub context_compacted: bool,
    pub cumulative_total: u32,
    pub compaction_from: Option<u32>,
}

Computed context window metrics for turn visualization.

Used by TUI and other presentation layers to show cumulative token usage and detect high-usage patterns.

Fields

turn_index: usize

Zero-based turn index.

prev_total: u32

Cumulative tokens before this turn (0 if context was compacted).

delta: u32

Tokens added by this turn (or new baseline if compacted).

is_heavy: bool

Whether this turn’s delta exceeds the heavy threshold.

is_active: bool

Whether this turn is currently active (in progress).

context_compacted: bool

True if context was compacted (reset) during this turn.

cumulative_total: u32

Actual cumulative tokens at end of this turn.

compaction_from: Option<u32>

Previous cumulative tokens before compaction (only set when context_compacted is true). Used to visualize the reduction (e.g., 150k → 30k).

Implementations

impl TurnMetrics

pub fn heavy_threshold(max_context: Option<u32>) -> u32

Calculate heavy threshold: 10% of max context, or fallback to 15k tokens

pub fn is_delta_heavy(delta: u32, max_context: Option<u32>) -> bool

Check if a delta is considered heavy

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

Performs copy-assignment from source.

impl Debug for TurnMetrics

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