Output
StreamingFast Substreams module outputs
Substreams
map
modules support a single output
. The output
must be a protobuf populated by data acquired inside the map
module. If the module intends to provide a basic output
type of a single value, such as a String
or bool
, a protobuf is still required. The single value needs to be wrapped in a protobuf for use as the output
value from a map
module.Note:
store
modules cannot define an output
.An
output
object has a type
attribute defining the type
of the output
for the map
module. The output
definition is located in the Substreams manifest, within the module definition.output:
type: proto:eth.erc721.v1.Transfers
