Struct OpenAIPromptCacheSettings 

pub struct OpenAIPromptCacheSettings {
    pub enabled: bool,
    pub min_prefix_tokens: u32,
    pub idle_expiration_seconds: u64,
    pub surface_metrics: bool,
    pub prompt_cache_key_mode: OpenAIPromptCacheKeyMode,
    pub prompt_cache_retention: Option<String>,
}

OpenAI prompt caching controls (automatic with metrics)

Fields

enabled: bool

min_prefix_tokens: u32

idle_expiration_seconds: u64

surface_metrics: bool

prompt_cache_key_mode: OpenAIPromptCacheKeyMode

Strategy for generating OpenAI prompt_cache_key. Session mode derives one stable key per VT Code conversation.

prompt_cache_retention: Option<String>

Optional prompt cache retention string to pass directly into OpenAI Responses API. Supported values are “in_memory” and “24h”. If set, VT Code will include prompt_cache_retention in the request body to extend the model-side prompt caching window or request the explicit in-memory policy.

Implementations

impl OpenAIPromptCacheSettings

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

Validate OpenAI provider prompt cache settings. Returns Err if the retention value is invalid.

fn clone(&self) -> OpenAIPromptCacheSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpenAIPromptCacheSettings

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

Formats the value using the given formatter.

impl Default for OpenAIPromptCacheSettings

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OpenAIPromptCacheSettings

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for OpenAIPromptCacheSettings

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
