Struct CacheBreakpoints 

pub struct CacheBreakpoints {
    pub after_system: bool,
    pub after_tools: bool,
    pub after_skills: bool,
    pub after_user_prompt: bool,
}

Marks the four section boundaries the runtime asks codecs to expose as cache breakpoints when the underlying provider supports them.

The order is fixed: system prompt, tool descriptions, skills, then the most recent user prompt. The “rest of the session” follows the last breakpoint and is therefore the only window eligible for in-band compaction by non-dedicated providers.

Fields

after_system: bool

after_tools: bool

after_skills: bool

after_user_prompt: bool

Implementations

impl CacheBreakpoints

pub fn all() -> Self

All four breakpoints active. The prompt assembler emits this layout for any session that has a non-empty system prompt and at least one user message; codecs may downgrade as needed.

pub fn count_active(&self) -> usize

Number of active breakpoints.

Trait Implementations

impl Clone for CacheBreakpoints

fn clone(&self) -> CacheBreakpoints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CacheBreakpoints

impl Debug for CacheBreakpoints

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

Formats the value using the given formatter.

impl Default for CacheBreakpoints

fn default() -> CacheBreakpoints

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CacheBreakpoints

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CacheBreakpoints

impl JsonSchema for CacheBreakpoints

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq for CacheBreakpoints

fn eq(&self, other: &CacheBreakpoints) -> 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 CacheBreakpoints

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
