Struct SessionSpec 

pub struct SessionSpec {
    pub provider: Option<ProviderHandle>,
    pub model: Option<String>,
    pub model_variant: Option<Option<String>>,
    pub execution_mode: Option<ExecutionMode>,
    pub max_context_tokens: Option<usize>,
    pub max_turns: Option<Option<usize>>,
    pub prompt: Option<PromptLayer>,
    /* private fields */
}

Reusable session configuration overlay.

SessionSpec is the public configuration shape for callers that want to describe either a root session or a child session without constructing the resolved runtime-only SessionPolicy directly.

Fields

provider: Option<ProviderHandle>

model: Option<String>

model_variant: Option<Option<String>>

execution_mode: Option<ExecutionMode>

max_context_tokens: Option<usize>

max_turns: Option<Option<usize>>

prompt: Option<PromptLayer>

Implementations

impl SessionSpec

pub fn new() -> Self

Create an explicit root-style spec. Unset fields resolve from the runtime’s core defaults.

pub fn inherit() -> Self

Create a parent-relative spec. Unset fields inherit from the live parent policy at resolution time.

pub fn inherits(&self) -> bool

pub fn provider(self, provider: ProviderHandle) -> Self

pub fn model(self, model: impl Into<String>, variant: Option<String>) -> Self

pub fn model_variant(self, variant: impl Into<String>) -> Self

pub fn clear_model_variant(self) -> Self

pub fn mode(self, mode: ExecutionMode) -> Self

pub fn max_context_tokens(self, max_context_tokens: usize) -> Self

pub fn max_turns(self, max_turns: usize) -> Self

pub fn clear_max_turns(self) -> Self

pub fn prompt_layer(self, prompt: PromptLayer) -> Self

pub fn resolve_against(&self, base: &SessionPolicy) -> SessionPolicy

Trait Implementations

impl Clone for SessionSpec

fn clone(&self) -> SessionSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionSpec

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

Formats the value using the given formatter.

impl Default for SessionSpec

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for SessionSpec

fn eq(&self, other: &SessionSpec) -> 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.
