monochange_semver

monochange_semver merges requested bumps with compatibility evidence.

Reach for this crate when you need deterministic severity calculations for direct changes, propagated dependent changes, or ecosystem-specific compatibility providers.

Why use it?

• combine manual change requests with provider-generated compatibility assessments
• share one bump-merging strategy across the workspace
• implement custom CompatibilityProvider integrations for ecosystem-specific evidence

Best for

• computing release severities outside the full planner
• plugging ecosystem-specific compatibility logic into shared planning
• reusing the workspace's bump-merging rules in custom tools

Responsibilities

• collect compatibility assessments from providers
• merge bump severities deterministically
• calculate direct and propagated bump severities
• provide a shared abstraction for ecosystem-specific compatibility providers

Example

use monochange_core::BumpSeverity;
use monochange_semver::direct_release_severity;
use monochange_semver::merge_severities;

let merged = merge_severities(BumpSeverity::Patch, BumpSeverity::Minor);
let direct = direct_release_severity(Some(BumpSeverity::Minor), None);

assert_eq!(merged, BumpSeverity::Minor);
assert_eq!(direct, BumpSeverity::Minor);
