Struct AssembledPrompt 

pub struct AssembledPrompt {
    pub segments: Vec<PromptSegment>,
    pub transcript: Vec<Message>,
    pub ordered_segments: Vec<PromptSegment>,
    pub prefix_cache_key: String,
    pub rendered_prefix: String,
    pub rendered_transcript: String,
    pub rendered: String,
    pub cache_breakpoints: CacheBreakpoints,
    pub system_segment_count: usize,
    pub skill_segment_count: usize,
}

Fully assembled prompt and transcript material ready for provider encoding.

Fields

segments: Vec<PromptSegment>

transcript: Vec<Message>

ordered_segments: Vec<PromptSegment>

prefix_cache_key: String

rendered_prefix: String

rendered_transcript: String

rendered: String

cache_breakpoints: CacheBreakpoints

Section boundaries that the assembler asks the codec to expose as cache breakpoints. Codecs that do not support explicit breakpoints (e.g. OpenAI Responses, which uses prefix-prefix caching) ignore this; codecs that do (Anthropic) emit cache_control on the last content block of each marked section.

system_segment_count: usize

Index into ordered_segments after which the system-prompt breakpoint applies. None when there are no system segments.

skill_segment_count: usize

Number of segments at the head of ordered_segments that belong to the skills section. Always immediately follows the system block.

Implementations

impl AssembledPrompt

pub fn system_segments(&self) -> &[PromptSegment]

Slice of segments that constitute the system-prompt section.

pub fn skill_segments(&self) -> &[PromptSegment]

Slice of segments that constitute the skills section.

pub fn append_segments(&self) -> &[PromptSegment]

Slice of segments that follow both the system and skills sections — hook-appended context, etc. These never receive a cache breakpoint because they may change turn-to-turn.

Trait Implementations

impl Clone for AssembledPrompt

fn clone(&self) -> AssembledPrompt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssembledPrompt

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AssembledPrompt

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for AssembledPrompt

impl JsonSchema for AssembledPrompt

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 AssembledPrompt

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
