Enum CacheControl 

pub enum CacheControl {
    Ephemeral {
        ttl: Option<String>,
    },
}

Cache control configuration for content caching (Anthropic-style)

Used to mark specific content blocks, messages, or tools for caching. Anthropic allows up to 4 cache breakpoints per request.

Example

use stakai::CacheControl;

// Default ephemeral cache (~5 min TTL)
let cache = CacheControl::ephemeral();

// Extended cache with 1-hour TTL
let cache = CacheControl::ephemeral_with_ttl("1h");

Variants

Ephemeral

Ephemeral cache that persists for a limited time

Default TTL is approximately 5 minutes. Use ttl to specify a longer duration (e.g., “1h” for 1-hour cache on Anthropic).

Fields

ttl: Option<String>

Optional TTL duration (e.g., “1h” for 1-hour cache)

Implementations

impl CacheControl

pub fn ephemeral() -> Self

Create ephemeral cache control with default TTL (~5 minutes)

Example

use stakai::CacheControl;

let cache = CacheControl::ephemeral();

pub fn ephemeral_with_ttl(ttl: impl Into<String>) -> Self

Create ephemeral cache control with custom TTL

Arguments

• ttl - Time-to-live duration (e.g., “1h” for 1 hour)

Example

use stakai::CacheControl;

let cache = CacheControl::ephemeral_with_ttl("1h");

pub fn has_ttl(&self) -> bool

Check if this cache control has an explicit TTL

pub fn ttl(&self) -> Option<&str>

Get the TTL if specified

Trait Implementations

impl Clone for CacheControl

fn clone(&self) -> CacheControl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheControl

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

Formats the value using the given formatter.

impl Default for CacheControl

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CacheControl

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CacheControl

fn eq(&self, other: &CacheControl) -> 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 Serialize for CacheControl

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CacheControl
