Struct CachePromptConfig 

pub struct CachePromptConfig {
    pub enabled: bool,
    pub min_content_length: usize,
    pub cache_system_prompt: bool,
    pub cache_last_n_messages: usize,
}

Configuration for automatic prompt cache control marking.

Fields

• enabled: Whether to apply cache control (default: true)
• min_content_length: Minimum message length to auto-cache (default: 1000)
• cache_system_prompt: Whether to cache system prompts (default: true)
• cache_last_n_messages: Number of recent user messages to cache (default: 3)

Example

use edgequake_llm::cache_prompt::CachePromptConfig;

// Use defaults
let config = CachePromptConfig::default();

// Custom configuration
let config = CachePromptConfig {
    enabled: true,
    min_content_length: 500,
    cache_system_prompt: true,
    cache_last_n_messages: 5,
};

Fields

enabled: bool

Whether cache control marking is enabled.

min_content_length: usize

Minimum content length (in characters) to auto-cache user messages.

Messages shorter than this threshold are not automatically cached unless they are system prompts or in the last N messages.

cache_system_prompt: bool

Whether to cache the system prompt.

System prompts rarely change and are excellent cache candidates.

cache_last_n_messages: usize

Number of recent user messages to cache.

Caching recent messages helps with conversation context retention.
