Struct DefaultCtx 

pub struct DefaultCtx {
    pub ctx_window: usize,
    /* private fields */
}

Fallback strategy — matches legacy behavior byte-for-byte.

Fields

ctx_window: usize

Token budget for this provider (from ProviderConfig.context_window, clamped to a defensive minimum of 8000 to avoid divide-by-zero and thrashing in pathological configs).

Implementations

impl DefaultCtx

pub fn new(provider: &ProviderConfig) -> Self

Construct a DefaultCtx from a provider config.

Trait Implementations

impl Clone for DefaultCtx

fn clone(&self) -> DefaultCtx

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CtxBuilder for DefaultCtx

fn build_messages( &self, conv: &Conversation, system_prompt: &str, turn_reminder: &str, ) -> (Vec<Message>, ContextStats)

Build the messages array to send to the LLM for this turn.

fn needs_compression(&self, conv: &Conversation, system_tokens: usize) -> bool

Whether the conversation should be compressed. Default: never.

fn compression_plan(&self, conv: &Conversation) -> Option<(String, usize)>

Produce a compression plan (content_to_summarize, messages_to_remove). Default: None (no compression).

fn truncate_tool_output(&self, result: &mut ToolResult, tool_name: &str)

Truncate a single tool output in place.

fn ctx_window(&self) -> usize

Effective token budget for this strategy.

fn name(&self) -> &'static str

Human-readable name for logging / debugging.

impl Debug for DefaultCtx

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

Formats the value using the given formatter.
