Struct ContextWindowStrategy 

pub struct ContextWindowStrategy { /* private fields */ }

Grounding strategy that limits injected context to a token budget.

Uses a simple 4-chars-per-token heuristic. Documents are added in order until the budget would be exceeded.

Example

use traitclaw_rag::{Document, GroundingStrategy};
use traitclaw_rag::hybrid::ContextWindowStrategy;

let large_doc = Document::new("d1", &"word ".repeat(1000));
let strategy = ContextWindowStrategy::new(50); // very small budget
let ctx = strategy.ground(&[large_doc]);
// Context is truncated to fit budget
assert!(ctx.chars().count() < 400); // 50 tokens * 4 chars each

Implementations

impl ContextWindowStrategy

pub fn new(max_tokens: usize) -> Self

Create a new ContextWindowStrategy with the given token budget.

Panics

Panics if max_tokens == 0.
