Struct TruncationInfo 

pub struct TruncationInfo {
    pub applied_limit: Option<usize>,
    pub items_content_truncated: usize,
    pub items_omitted: usize,
    pub estimated_tokens: Option<usize>,
    pub suggestion: Option<String>,
}

Describes how a FetchOutput was bounded. A summary so an agent can tell at a glance that it is not seeing the full, untruncated result and how to adjust.

Fields

applied_limit: Option<usize>

The item cap actually applied (e.g. the MCP default of 25), or null if none.

items_content_truncated: usize

Number of items whose content was truncated (e.g. by max_content_chars).

items_omitted: usize

Number of items dropped entirely to fit a response budget. 0 unless the server shed items (a Tier-2 behavior; always 0 in the cap-and-error path).

estimated_tokens: Option<usize>

Rough token estimate of the (possibly reduced) serialized response, if computed.

suggestion: Option<String>

Human/agent-facing hint on how to adjust the request (e.g. which knob to pass).

Trait Implementations

impl Clone for TruncationInfo

fn clone(&self) -> TruncationInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TruncationInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TruncationInfo

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for TruncationInfo

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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
