Feature request: resolve event signature string (needed for indexers)

[PaulRBerg]

Event Signature String

Feature request: provide a function that takes an AbiEvent input and generates an event signature string, e.g.

Approval(indexed address,indexed address,uint256)

Why?

Such a function would be incredibly helpful for generating indexer manifests, e.g., the YAML subgraph manifests used by The Graph.

Suggested Names

Instead of signature, we could also say sig:

• deriveEventSignature
• getEventSignature
• resolveEventSignature

Demo Implementation

I've already written my own implementation:

For which I've also written some tests:
