Struct libalpm::Db

pub struct Db<'a> { /* fields omitted */ }

A database of packages. This is only ever available as a reference

Methods

impl<'a> Db<'a>

fn name(&self) -> Result<&'a str, Utf8Error>

Gets the name of the database.

fn siglevel(&self) -> SigLevel

Gets the signature checking level of the database.

fn is_valid(&self) -> AlpmResult<()>

Checks the database is valid. If not, an error

fn servers(&self) -> Vec<&str>

Gets a list of the servers used by the database.

fn set_servers<R>(&self, servers: Vec<R>) -> AlpmResult<()> where
    R: AsRef<str>, 

Sets the servers used by the database.

fn add_server(&self, url: &str) -> AlpmResult<()>

Adds a server to the list of servers used by the database.

fn remove_server(&self, url: &str) -> AlpmResult<()>

Removes a server from the list of servers used by the database.

fn update(&self, force: bool) -> AlpmResult<()>

Update (sync) the database with remote.

If force is set to false and the database is up to date the function will return successfully without doing anything.

fn pkg(&self, name: &str) -> AlpmResult<&'a PackageRef>

Gets a package with the given name from the database

fn pkg_cache(&self) -> Vec<&PackageRef>

Gets all packages in the db cache

fn group(&self, name: &str) -> AlpmResult<Group<'a>>

Gets a package group from the database by name.

fn group_cache(&self) -> AlpmResult<Vec<Group<'a>>>

Gets the package group cache of the database.

fn search(&self, needles: Vec<&str>) -> AlpmResult<Vec<&PackageRef>>

Searches the database for packages matching the needles.

This function has a memory leak, but I'm 99% sure it's internal to libalpm. Needs more testing.

fn set_usage(&self, usage: Usage) -> AlpmResult<()>

Sets what this database is to be used for.

fn usage(&self) -> AlpmResult<Usage>

Gets what this database is to be used for.

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
