Treatment fromJson

json/value::fromJson

Generics

◻ T: Deserialize

Inputs

⇥ json: Stream<Json> (json::Json)

Outputs

↦ value: Stream<Option<T>>

Emit each JSON value of the stream as a value of type T, or none if it cannot be one.

Numbers, booleans, strings and null (for void) become the core types they fit in, arrays become vectors, null becomes none for options, and data types are read as they define, such as StringMap from an object of strings. Secrets are never read from JSON.
