Struct StreamDescriptor 

pub struct StreamDescriptor {
    pub source_key: String,
    pub source_name: String,
    pub source_path: String,
    pub metadata: Value,
    pub measurement_type: Option<String>,
    pub sensor_id: Option<Uuid>,
    pub replicates: Option<ReplicateSpec>,
    pub decimal_places: Option<i16>,
}

Describes a data stream to register with river-data.

Fields

source_key: String

Unique key within the source system (ie. a location id or column name).

source_name: String

Human-readable name shown in the dashboard.

source_path: String

Hierarchy path (ie. “cnet/VAD/WTW_DO_mgL_1”), parsed server-side for site discovery.

metadata: Value

measurement_type: Option<String>

Stream classification (‘spot’ or ‘continuous’); None defers to the API’s resolution chain.

sensor_id: Option<Uuid>

Owning sensor; required for streams whose readings carry curve claims.

replicates: Option<ReplicateSpec>

Replicate-family declaration; requires measurement_type: "spot".

decimal_places: Option<i16>

The decimal places the source stores or presents this channel at. Pairing writes it onto the slot where none is declared, and the public API expresses served values at it. None leaves the slot undeclared, which is served unrounded.
