Enum InputSource 

#[non_exhaustive]
pub enum InputSource {
    Inline {
        value: Value,
    },
    Reference {
        data_ref: DataRef,
    },
}

How input data is provided to a worker.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Inline

Data embedded directly in the message (small payloads).

Fields

value: Value

The value itself, carried in the message.

Reference

Data referenced in a remote store (large payloads).

Fields

data_ref: DataRef

Where to fetch the value from; see InputSource::resolve.

Implementations

impl InputSource

pub fn resolve( &self, data_store: Option<&dyn DataStore>, temp_store: &LocalDataStore, ) -> Result<Value>

Resolve the input to a concrete Value.

Tries the persistent DataStore first, then the temp store that HTTP uploads land in.

A reference that resolves nowhere is an error, and it did not used to be: this logged a warning and returned [Value::Empty]. That value went on to the filter, so the failure surfaced as a TypeError inside somebody’s own fit — hundreds of thousands of rows after the actual problem, and pointing at their code. The usual cause is the asymmetry this error names: the client uploaded to a store the worker was never given.

Trait Implementations

impl<'de> Deserialize<'de> for InputSource

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for InputSource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,
