[−][src]Enum pkgsrc::MetadataEntry
Type of Metadata entry.
Package metadata stored either in a package archive or inside a package
entry in a PkgDB::DBType::Files
package database is contained in various
files prefixed with +
.
This enum supports all of those filenames and avoids having to hardcode their values. It supports converting to and from the filename or enum.
Example
use pkgsrc::MetadataEntry; let e = MetadataEntry::Desc; /* * Validate that the `Desc` entry matches our expected filename. */ assert_eq!(e.to_filename(), "+DESC"); assert_eq!(MetadataEntry::from_filename("+DESC"), Some(e)); /* * This is not a known +FILE */ assert_eq!(MetadataEntry::from_filename("+BADFILE"), None);
Variants
Optional package build information stored in +BUILD_INFO
.
Optional version information (usually CVS Id's) for the files used to
create the package stored in +BUILD_VERSION
.
Single line description of the package stored in +COMMENT
.
Packing list contents, also known as the packlist
or PLIST
, stored
in +CONTENTS
.
Optional script executed upon deinstall, stored in +DEINSTALL

.
Optional file, also known as MESSAGE
, to be shown during package
install or deinstall, stored in +DISPLAY
.
Optional script executed upon install, stored in +INSTALL
.
Variables set by this package, currently only automatic=yes

supported, stored in +INSTALLED_INFO
.
Obsolete file used to pre-create directories prior to a package install,
stored in +MTREE_DIRS
.
Optional marker that this package should not be deleted under normal
circumstances, stored in +PRESERVE
.
Optional list of packages that are reverse dependencies of (i.e. depend
upon) this package, stored in +REQUIRED_BY
.
Optional size of this package plus all of its dependencies, stored in

Methods
impl MetadataEntry
[src]
pub fn to_filename(&self) -> &str
[src]
Return filename for the associated MetadataEntry
type.
Example
use pkgsrc::MetadataEntry; let e = MetadataEntry::Contents; assert_eq!(e.to_filename(), "+CONTENTS");
pub fn from_filename(file: &str) -> Option<MetadataEntry>
[src]
Return MetadataEntry
enum in an Option for requested file.
Example
use pkgsrc::MetadataEntry; assert_eq!(MetadataEntry::from_filename("+CONTENTS"), Some(MetadataEntry::Contents)); assert_eq!(MetadataEntry::from_filename("+BADFILE"), None);
