Enum CacheStrategy 

pub enum CacheStrategy {
    Disabled,
    SystemOnly,
    MessagesOnly,
    Full,
}

Cache strategy determining which content types to cache.

Anthropic best practices recommend caching static content (system prompts, tools) with longer TTLs and dynamic content (messages) with shorter TTLs.

Variants

Disabled

No caching - all content sent without cache_control

SystemOnly

Cache system prompt only (static content with long TTL)

MessagesOnly

Cache messages only (last user turn with short TTL)

Full

Cache both system and messages (recommended)

Implementations

impl CacheStrategy

pub fn cache_system(&self) -> bool

Returns true if system prompt caching is enabled

pub fn cache_messages(&self) -> bool

Returns true if message caching is enabled

pub fn is_enabled(&self) -> bool

Returns true if any caching is enabled

Trait Implementations

impl Clone for CacheStrategy

fn clone(&self) -> CacheStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheStrategy

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

Formats the value using the given formatter.

impl Default for CacheStrategy

fn default() -> CacheStrategy

Returns the “default value” for a type.

impl PartialEq for CacheStrategy

fn eq(&self, other: &CacheStrategy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for CacheStrategy

impl Eq for CacheStrategy

impl StructuralPartialEq for CacheStrategy
