pub struct ContextBuilder { /* private fields */ }Expand description
Context builder that assembles memories into structured prompts.
Implementations§
Source§impl ContextBuilder
impl ContextBuilder
Sourcepub fn new(counter: Box<dyn TokenCounter>) -> Self
pub fn new(counter: Box<dyn TokenCounter>) -> Self
Create a new builder with the given token counter.
Sourcepub fn estimate_tokens(&self, text: &str) -> usize
pub fn estimate_tokens(&self, text: &str) -> usize
Estimate token count for text using the internal counter.
Sourcepub fn build(
&self,
template: &PromptTemplate,
memories: &[MemoryEntry],
strategy: Strategy,
) -> String
pub fn build( &self, template: &PromptTemplate, memories: &[MemoryEntry], strategy: Strategy, ) -> String
Build a prompt string from template, filling memory slots with
memories according to strategy.
Returns the assembled prompt as a single String. Sections that end
up empty (no fixed content and no memories fit) are omitted entirely.
Sections whose content exceeds their max_tokens budget are truncated
with "...[truncated]".
