Struct GuestRuntimeKit 

pub struct GuestRuntimeKit {
    pub truth: Arc<dyn TruthPolicy>,
    pub coerce: Arc<dyn CoercionPolicy>,
    pub nil: Value,
}

Runtime policy bundle a language profile configures once and reuses.

Fields

truth: Arc<dyn TruthPolicy>

Truthiness policy for this profile.

coerce: Arc<dyn CoercionPolicy>

Boundary coercion policy for this profile.

nil: Value

Profile-specific nil value used for arity padding.

Implementations

impl GuestRuntimeKit

pub fn new( truth: Arc<dyn TruthPolicy>, coerce: Arc<dyn CoercionPolicy>, nil: Value, ) -> Self

Build a kit from truthiness, coercion, and nil policies.

pub fn is_truthy(&self, cx: &mut Cx, value: &Value) -> Result<bool>

Return whether value counts as truthy for this profile.

pub fn to_number(&self, cx: &mut Cx, value: &Value) -> Result<Option<Value>>

Convert value to a number value when this profile accepts such a coercion.

pub fn to_string(&self, cx: &mut Cx, value: &Value) -> Result<Option<Value>>

Convert value to a string value when this profile accepts such a coercion.

pub fn adjust_values(&self, values: Vec<Value>, rule: Arity) -> Vec<Value>

Apply an arity rule using this profile’s nil value for padding.
