Struct RpmLicenseFilesParser 

pub struct RpmLicenseFilesParser;

Parser for RPM license files in /usr/share/licenses/ directories.

Identifies packages from their license files installed in the standard /usr/share/licenses/ location, primarily used in Mariner distroless containers.

Supported Formats

• /usr/share/licenses/*/COPYING* - COPYING license files
• /usr/share/licenses/*/LICENSE* - LICENSE files

Key Features

• Extracts package name from directory path
• Supports Mariner distroless container convention
• Package URL generation with mariner namespace

Implementation Notes

• Package name is extracted from the directory between licenses/ and the filename
• For example: /usr/share/licenses/openssl/LICENSE → package name is “openssl”
• Does NOT perform license detection (that’s handled by the license scanner)
• datasource_id: “rpm_package_licenses”
• namespace: “mariner”
