Struct Interpolated 

pub struct Interpolated { /* private fields */ }

A document of var holes in otherwise literal data, $ keys kept verbatim. It is for payloads such as a MongoDB filter, where $oid is data and {"var": ...} is the only live part.

Any other operator-shaped node, val included, stays data and is reported as OPERATOR_IN_DOCUMENT; a secret node is refused as SECRET_IN_DOCUMENT. A hole’s default is data too, and is checked the same way.

Implementations

impl Interpolated

pub fn raw(&self) -> &Value

The document as authored, as a serde_json::Value, its objects’ keys in the order they were written: the crate turns on serde_json’s preserve_order.

pub fn holes(&self) -> impl Iterator<Item = &Path>

The paths the holes read, in document order. A hole rooted at payload reads nothing and is not listed.

Trait Implementations

impl ConfigField for Interpolated

const NULL_IS_VALUE: bool = true

null is a document with no hole.

fn resolve(&self, r: &mut dyn Resolver) -> Result<Option<OwnedDataValue>>

The document rendered for this call.

fn compile(raw: &Value, cx: &mut CompileCx<'_>) -> Option<Self>

Compiles raw; None after recording at least one issue.

fn visit(&self, v: &mut Visit<'_>)

Reports the field’s expressions.

fn kind() -> FieldKind

What the field is.

const IS_OUTPUT: bool = false

Whether the field is an output: a destination its call writes to. false unless the type is Output or an Option of one. The derive reads a field typed Output or marked #[output] as an output and asserts that this is true, so a type that merely shares the name is refused at compile time.

fn absent() -> Option<Self>

The value when the key is absent and no default is declared. None makes the field required.

impl Debug for Interpolated

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

Formats the value using the given formatter.
