Struct SystemInjector 

pub struct SystemInjector { /* private fields */ }

Injects system prompt content based on turn or token thresholds.

Add rules with SystemInjector::add_rule, then call SystemInjector::check each turn to get any content that should be injected.

Example

use neuron_context::{SystemInjector, InjectionTrigger};

let mut injector = SystemInjector::new();
injector.add_rule(InjectionTrigger::EveryNTurns(5), "Reminder: be concise.".into());
injector.add_rule(InjectionTrigger::OnTokenThreshold(50_000), "Context is getting long.".into());

// Turn 5, under token threshold
let injected = injector.check(5, 10_000);
assert!(injected.contains(&"Reminder: be concise.".to_string()));

// Turn 1, over token threshold
let injected = injector.check(1, 60_000);
assert!(injected.contains(&"Context is getting long.".to_string()));

Implementations

impl SystemInjector

pub fn new() -> Self

Creates a new SystemInjector with no rules.

pub fn add_rule(&mut self, trigger: InjectionTrigger, content: String)

Adds an injection rule.

Arguments

• trigger — when this rule fires
• content — the text to inject when triggered

pub fn check(&self, turn: usize, token_count: usize) -> Vec<String>

Returns all content strings whose triggers are satisfied by the given state.

Arguments

• turn — the current turn number (1-indexed for “every N” checks)
• token_count — the current estimated token count

Trait Implementations

impl Default for SystemInjector

fn default() -> SystemInjector

Returns the “default value” for a type.
