Overview

Resolves requested version identifiers to actual version objects

The VersionResolver handles version resolution logic, finding the appropriate version to use based on a requested version identifier. It implements a “downgrading” strategy - when an exact version match isn’t found, it returns the closest earlier version.

Examples:

Resolving a version

versions = ["2025-01", "2025-06", "2026-01"]

# Exact match
Verquest::VersionResolver.call("2025-06", versions) # => "2025-06"

# Between versions - returns previous version
Verquest::VersionResolver.call("2025-04", versions) # => "2025-01"

# After latest version - returns latest
Verquest::VersionResolver.call("2026-06", versions) # => "2026-01"

Class Method Details

.call(requested_version, versions) ⇒ String?

Resolves a requested version to the appropriate available version

This method implements the version resolution strategy:

  • If an exact match is found, that version is returned

  • If the requested version is between two available versions, the earlier one is returned

  • If the requested version is after all available versions, the latest version is returned
