Struct ProjectedValue 

pub struct ProjectedValue { /* private fields */ }

Implementations

impl ProjectedValue

pub fn scalar(name: impl Into<Arc<str>>, value: Value) -> Self

pub fn custom( name: impl Into<Arc<str>>, value: Arc<dyn ProjectedHostDescriptor>, ) -> Self

pub fn custom_with_projection_ref( name: impl Into<Arc<str>>, value: Arc<dyn ProjectedHostDescriptor>, projection_ref: Value, ) -> Self

pub fn name(&self) -> &str

pub fn projection_ref(&self) -> Option<&Value>

pub fn propagate_field(parent_name: &str, field: &str, inner: Value) -> Value

Wrap a derived value as a ProjectedValue carrying a path-extended name (e.g. parent.field). Pass-through if the inner value is already a Value::Projected so we never double-wrap. Used by field/index access on projected sources to keep “this came from a projected source” alive across path expressions; non-path operations (binary ops, builtins, formatters) auto-strip via their existing materialise-and-evaluate code paths and so naturally lose the wrapper.

pub fn propagate_index(parent_name: &str, index: &Value, inner: Value) -> Value

pub async fn render(&self) -> String

pub async fn materialize_async(&self) -> Value

pub fn materialize(&self) -> Value

Trait Implementations

impl Clone for ProjectedValue

fn clone(&self) -> ProjectedValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectedValue

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

Formats the value using the given formatter.

impl PartialEq for ProjectedValue

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