Struct LegacyCatalog 

pub struct LegacyCatalog { /* private fields */ }

The audited catalog of pre-schema releases.

Implementations

impl LegacyCatalog

pub fn embedded() -> Self

The catalog this binary carries.

A catalog that does not parse is a build defect rather than a state a command can meet, and the canon suite parses the same bytes.

Panics

Never in a shipped build, for the reason above.

pub fn entry(&self, version: &str) -> Option<&CatalogEntry>

What the catalog says about one version.

pub const fn index(&self) -> &CatalogIndex

The index itself, for the canon suite and the diagnostics.

pub const fn descriptors(&self) -> &BTreeMap<String, String>

Every descriptor, by version.

pub fn descriptor( &self, version: &str, ) -> Result<(Descriptor, Sha256), AppError>

The descriptor one version resolves to, checked against the index.

Errors

AppError::Refused when the version is unavailable, uncataloged, or whose descriptor no longer matches the digest the index records.

pub fn adapt( &self, version: &str, files: &BTreeMap<String, Vec<u8>>, ) -> Result<Adapted, AppError>

Overlay a descriptor’s facts onto one pre-schema archive.

Errors

AppError::Refused when the version is not cataloged, when the descriptor disagrees with the archive it describes, or when the overlay cannot be rendered.
