Struct srcinfo::Srcinfo

pub struct Srcinfo {
    pub base: PackageBase,
    pub pkg: Package,
    pub pkgs: Vec<Package>,
}

A complete representation of a .SRCINFO file.

Fields

base: PackageBase

Fields belonging to the pkgbase

pkg: Package

Fields belonging to the pkgbase, may be overridden inside of each package

pkgs: Vec<Package>

The packages this .SRCINFO contains

Implementations

impl Srcinfo

pub fn parse_buf<T: BufRead>(b: T) -> Result<Srcinfo, Error>

Parse a BufRead. If you are parsing a string directly from_str() should be used instead.

// from_str() would be better here.
// parse_buf() is only used for the sake of example.
use srcinfo::Srcinfo;

let buf = "
pkgbase = example
pkgver = 1.5.0
pkgrel = 5

pkgname = example".as_bytes();

Srcinfo::parse_buf(buf)?;

pub fn parse_file<P: AsRef<Path>>(s: P) -> Result<Srcinfo, Error>

Parse the file at a given path.

use srcinfo::Srcinfo;

let file = ".SRCINFO";
let srcinfo = Srcinfo::parse_file(file)?;

pub fn version(&self) -> String

Builds a complete version string in the format: "epoch-pkgver-pkgrel".

If the epoch is none then the epoch and connecting hyphen will be omitted.

use srcinfo::Srcinfo;

let srcinfo: Srcinfo = "
pkgbase = example
pkgver = 1.5.0
pkgrel = 5

pkgname = example".parse()?;

assert_eq!(srcinfo.version(), "1.5.0-5");

pub fn names(&self) -> impl Iterator<Item = &str>

Returns an Iterator over all the pkgnames the Package contains.

use srcinfo::Srcinfo;

let srcinfo: Srcinfo = "
pkgbase = example
pkgver = 1.5.0
pkgrel = 5
pkgdesc = 1

pkgname = example

pkgname = foo
pkgdesc = 2

pkgname = bar
pkgdesc = 3".parse()?;

let mut names = srcinfo.names().collect::<Vec<_>>();
assert_eq!(names, vec!["example", "foo", "bar"]);

pub fn pkg<S: AsRef<str>>(&self, name: S) -> Option<&Package>

Searches for a package with a given pkgname

use srcinfo::Srcinfo;

let srcinfo: Srcinfo = "
pkgbase = example
pkgver = 1.5.0
pkgrel = 5
pkgdesc = 1

pkgname = example

pkgname = foo
pkgdesc = 2

pkgname = bar
pkgdesc = 3".parse()?;

let pkg = srcinfo.pkg("foo").unwrap();
assert_eq!(pkg.pkgname, "foo");
