Enum PackageBaseProperty

pub enum PackageBaseProperty {
    EmptyLine,
    Comment(String),
    MetaProperty(SharedMetaProperty),
    PackageVersion(PackageVersion),
    PackageRelease(PackageRelease),
    PackageEpoch(Epoch),
    ValidPgpKeys(OpenPGPIdentifier),
    RelationProperty(RelationProperty),
    CheckDependency(ArchProperty<PackageRelation>),
    MakeDependency(ArchProperty<PackageRelation>),
    SourceProperty(SourceProperty),
}

All possible properties of a pkgbase section in SRCINFO data.

The ordering of the variants represents the order in which keywords would appear in a SRCINFO file. This is important as the file format represents stateful data which needs normalization.

The SRCINFO format allows comments and empty lines anywhere in the file. To produce meaningful error messages for the consumer during data normalization, the line number on which an error occurred is encoded in the parsed data.

Implementations

impl PackageBaseProperty

fn parser(input: &mut &str) -> ModalResult<PackageBaseProperty>

Recognizes any line in the pkgbase section of SRCINFO data.

This is a wrapper to separate the logic between comments/empty lines and actual pkgbase properties.

fn property_parser(input: &mut &str) -> ModalResult<PackageBaseProperty>

Recognizes keyword assignments in the pkgbase section in SRCINFO data.

Since there’re a lot of keywords and many of them are shared between the pkgbase and pkgname section, the keywords are bundled into somewhat logical groups.

• SourceProperty are keywords that are related to the source keyword, such as checksums.
• SharedMetaProperty are keywords that are related to general meta properties of the package.
• RelationProperty are keywords that describe the relation of the package to other packages. RawPackageBase has two special relations that are explicitly handled in Self::exclusive_property_parser.
• Other fields that’re unique to the RawPackageBase are handled in Self::exclusive_property_parser.

fn keyword_parser(input: &mut &str) -> ModalResult<PackageBaseKeyword>

Recognizes a PackageBaseKeyword in an input string slice.

fn exclusive_property_parser( input: &mut &str, ) -> ModalResult<PackageBaseProperty>

Recognizes keyword assignments exclusive to the pkgbase section in SRCINFO data.

This function backtracks in case no keyword in this group matches.
