missing resource name

Error message

missing resource name {0}

What it means

ResourceMappingError::MissingResourceName is thrown when a resource entry that should carry a name has none — the name string is empty or absent during resource mapping. The mapping layer requires every non-wildcard resource entry to identify itself by name.

Solutions

1. Ensure every non-wildcard resource entry has a non-empty name before calling the mapping API.
2. Validate permission definitions at load time and reject entries with empty names.
3. Fix the template/config that produced an empty name value.

Example fix

// before
let names = vec![""]; // missing
// after
let names = vec!["my_db"];

fn require_name(entry: &PermissionEntry) -> Result<&str, String> {
    entry.name.as_deref().filter(|n| !n.trim().is_empty()).ok_or_else(|| "missing resource name".to_string())
}

let name = require_name(&entry).map_err(ResourceMappingError::MissingResourceName)?;

When it happens

Trigger: Passing an empty string or a record with a missing name field into the resource-name-to-id mapping when building token permissions.

Common situations: Deserialized permission JSON with a null/empty "name"; config templating that left a placeholder unsubstituted; programmatic construction skipping the name field.
