Struct LogReader 

pub struct LogReader { /* private fields */ }

Implementations

impl LogReader

pub fn open<P: AsRef<Path>>(path: P) -> Self

Create a log reader for the file at the specified path.

The file is opened when iteration begins. If the file does not exist or is not readable, the first iteration will return an error.

pub fn system() -> Self

Create a log reader for the system pacman log at /var/log/pacman.log.

pub fn reverse(self) -> Self

Read entries in reverse order (most recent first).

pub fn filter_action(self, action: Action) -> Self

Filter entries by action type.

pub fn filter_package(self, package: &str) -> Self

Filter entries by package name (substring match).

pub fn filter_package_exact(self, package: &str) -> Self

Filter entries by exact package name.

pub fn since(self, timestamp: DateTime<FixedOffset>) -> Self

Filter entries since the given timestamp (inclusive).

pub fn until(self, timestamp: DateTime<FixedOffset>) -> Self

Filter entries until the given timestamp (inclusive).

pub fn entries(self) -> impl Iterator<Item = Result<Entry>>

Iterate over every log line as an Entry, in forward order.

Unlike the IntoIterator impl, this yields all line types (commands, transaction markers, hook and scriptlet output) and ignores the filters.

pub fn transactions(self) -> impl Iterator<Item = Result<Transaction>>

Group package operations into transactions, in forward order.

Each Transaction is delimited by the transaction started and transaction completed markers and tagged with the most recent pacman command logged before it. A transaction left open by a truncated log is still yielded, with completed set to None.

Trait Implementations

impl IntoIterator for LogReader

type Item = Result<LogEntry, Error>

The type of the elements being iterated over.

type IntoIter = Box<dyn Iterator<Item = Result<LogEntry, Error>>>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
