Enum InjectedValue 

pub enum InjectedValue {
    PartitionId,
    Constant(Value),
    FromPrincipal(String),
    FromHeader(String),
}

How an InjectedField’s value is computed for a document.

Not #[non_exhaustive]: the proxy must resolve every value kind to inject a concrete value, so a new kind should force the resolver to be updated.

Variants

PartitionId

The resolved partition id. This is the isolation value: the read path filters on it, so it must be deterministic (the partition), not context-derived. Exactly the fields whose value is PartitionId drive read isolation.

Constant(Value)

A fixed JSON value, the same for every document.

FromPrincipal(String)

A named attribute of the authenticated principal, resolved per request. A decorative value: injected on write and stripped on read, never used as a read filter (its value can differ between the write and the read).

FromHeader(String)

A named request header, resolved per request. Decorative like InjectedValue::FromPrincipal: injected and stripped, never filtered. Lets injection be dynamic from request context (e.g. a _region field taken from an x-region header set by an upstream gateway).

Trait Implementations

impl Clone for InjectedValue

fn clone(&self) -> InjectedValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InjectedValue

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

Formats the value using the given formatter.

impl Eq for InjectedValue

impl PartialEq for InjectedValue

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