Struct ContextWindow 

pub struct ContextWindow {
    pub used: Option<Percent>,
    pub size: Option<u32>,
    pub total_input_tokens: Option<u64>,
    pub total_output_tokens: Option<u64>,
    pub current_usage: Option<TurnUsage>,
}

Fields

used: Option<Percent>

Used percentage. remaining() derives from this. Per ADR-0014, None when CC emits used_percentage: null (the pre-first-API- call window, see docs/research/context-window-correctness.md) or the leaf is otherwise malformed.

size: Option<u32>

Context-window size in tokens. u32 matches ADR-0014’s Shape section; values outside the u32 range degrade to None.

total_input_tokens: Option<u64>

total_output_tokens: Option<u64>

current_usage: Option<TurnUsage>

Tokens consumed by the most recent API call; None before the first call in a session. Distinct from total_*_tokens above, which are cumulative across the whole session.

Implementations

impl ContextWindow

pub fn remaining(&self) -> Option<Percent>

Percentage remaining; always consistent with used. Returns None when used is None (per-leaf Option per ADR-0014).
