v1.0.0

Highlights

• Added command substreams gui, providing a terminal-based GUI to inspect the streamed data. Also adds --replay support, to save a stream to replay.log and load it back in the UI later. You can use it as you would substreams run. Feedback welcome.
• Modified command substreams protogen, defaulting to generating the mod.rs file alongside the rust bindings. Also added --generate-mod-rs flag to toggle mod.rs generation.
• Added support for module parameterization. Defined in the manifest as:

module:
  name: my_module
  inputs:
    params: string
  ...
  
params:
  my_module: "0x123123"
  "imported:module": override value from imported module

and on the command-line as:

• substreams run -p module=value -p "module2=other value" ...

Servers need to be updated for packages to be able to be consumed this way.

This change keeps backwards compatibility. Old Substreams Packages will still work the same, with no changes to module hashes.

Added

• Added support for {version} template in --output-file flag value on substreams pack.
• Added fuel limit to wasm execution as a server-side option, preventing wasm process from running forever.
• Added 'Network' and 'Sink{Type, Module, Config}' fields in the manifest and protobuf definition for future bundling of substreams sink definitions within a substreams package.
