pub fn config_validate(
config_path: Option<&Path>,
args: &ConfigValidateArgs,
) -> Result<()>Expand description
Validate a configuration and print a resolved summary.
Runs the daemon’s resolver against the same TOML + CLI + env-var
inputs decdn-node run would use, then prints the result. Does not
bind any ports, does not connect to the JSON-RPC endpoint, and does
not open the cache. Does touch the filesystem to verify the config
itself: reads the TOML, and stats / opens the configured
blockchain.eth_keystore for readability (the resolver rejects
missing paths, directories, and broken symlinks at this point so
the daemon doesn’t fail later in startup).
