Module schema 

Schema version parsing and compatibility validation for shipper state files.

This module was folded in from the former shipper-schema crate in Phase 6 of the decrating effort (see docs/decrating-plan.md). Schema version parsing and compatibility validation for shipper state files.

Shipper persists state and receipt files on disk with a version tag in the form shipper.<doctype>.v<N> (for example, shipper.receipt.v2). This module provides the parsing and compatibility helpers used when loading those files.

Historically these helpers lived in a dedicated shipper-schema crate. Phase 6 of the decrating effort folded that crate in here because the public surface was only two functions with no independent consumers.

Examples

use shipper_types::schema::{parse_schema_version, validate_schema_version};

assert_eq!(parse_schema_version("shipper.receipt.v2").unwrap(), 2);
assert!(validate_schema_version(
    "shipper.receipt.v2",
    "shipper.receipt.v1",
    "receipt",
)
.is_ok());

Functions

parse_schema_version

Parse schema version number from a string like shipper.receipt.v2.

validate_schema_version

Validate that version is at least the minimum supported schema version.
