Module package 

Versioned package metadata and manifest classification.

Structs

PackageMetadata

Package metadata carried by mars.toml.

Enums

ManifestClassification

The schema dispatch result for a package root’s optional mars.toml.

Constants

SCHEMA_1_MARS_FLOOR

The first Mars release that reads schema 1. An older one reads a schema = 1 package as pre-v1, so a schema v1 package’s requires-mars may not admit one.

Functions

classify_manifest

Classify manifest bytes before any package content is lifted or discovered.

parse_requirement

Parse a requires-mars or requires-meridian requirement. A bare version means >= it (0.19.0 is >=0.19.0), as mars.toml documents both fields.

requirement_has_floor

Whether requirement demands at least floor, so a Mars older than one floor cannot read the package. A range with no lower bound (<0.25) does not; an unparseable one cannot say.

requires_mars_floor_warning

The advice for a requirement that is missing or admits a Mars older than floor. None when it does not, or when it is not a requirement this Mars can read: a broken requirement is its own error.

schema_1_requires_mars_warning

The advice mars check prints for a schema v1 package’s requires-mars, which mars migrate prints with it when it leaves an authored requirement alone.
