Enum ContextCompression 

pub enum ContextCompression {
    MiddleOut,
}

Which context-compression engine to enable on outgoing OpenRouter chat-completions requests. Maps onto OpenRouter’s request-body plugins array — see https://openrouter.ai/docs/features/middle-out.

Variants

MiddleOut

Middle-out compression — drops content from the middle of the conversation when the request would otherwise exceed the model’s context window. The only engine documented today.

Intentionally no #[schemars(title)] here: the builder’s single-variant-anyOf flatten merges the variant’s title onto the parent schema, clobbering the enum’s agent.openrouter .ContextCompression rename. Add a per-variant title only once a second variant lands.

Implementations

impl ContextCompression

pub fn prepare(self) -> Option<Self>

Hook used during agent ID computation. There’s no default-to- collapse for this field — every variant is meaningful — so we pass the value through unchanged.

pub fn validate(&self) -> Result<(), String>

Validates the setting (always succeeds — every variant is inhabited by a documented OpenRouter engine).

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for ContextCompression

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for ContextCompression

fn clone(&self) -> ContextCompression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ContextCompression

impl Debug for ContextCompression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ContextCompression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ContextCompression

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

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 inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ContextCompression

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
