Struct SlidingWindow 

pub struct SlidingWindow { /* private fields */ }

Sliding window context strategy.

When context exceeds the limit, drops the oldest messages (keeping the first message, which is typically the initial user message).

Implementations

impl SlidingWindow

pub fn new() -> Self

Create a new sliding window strategy.

chars_per_token controls the token estimation granularity (default: 4 chars per token).

pub fn with_ratio(chars_per_token: usize) -> Self

Create with a custom chars-per-token ratio.

fn should_compact(&self, messages: &[ProviderMessage], limit: usize) -> bool

Whether compaction should run given the current messages and limit.

fn compact(&self, messages: Vec<ProviderMessage>) -> Vec<ProviderMessage>

Compact the message list. Returns a shorter list.

impl Default for SlidingWindow

fn default() -> Self

Returns the “default value” for a type.
