Function validate_plugin_package_name 

pub fn validate_plugin_package_name(
    name: &str,
) -> Result<(), InvalidPluginPackageName>

Validate the package-name grammar shared by manifests, configuration, and runtime instance construction.

One grammar keeps [channels.plugin.<alias>].package and the installed manifest’s name on the same spelling, so a declaration that passes config validation cannot fail to match an admitted package for a reason the operator never sees. The grammar is deliberately narrow: no uppercase, no path separators, and no whitespace or control characters, so a package name can be embedded in a log field or a derived key without quoting.

Errors

Returns InvalidPluginPackageName when name is empty, longer than 128 bytes, or is not a lowercase ASCII slug with supported separators.
