Struct JournalQuery 

pub struct JournalQuery { /* private fields */ }

A query builder for reading entries from a Journal.

Implementations

impl JournalQuery

pub fn match_exact(&mut self, field: &str, value: &[u8]) -> &mut Self

pub fn match_present(&mut self, field: &str) -> &mut Self

pub fn or_group<F>(&mut self, f: F) -> &mut Self

where F: FnOnce(&mut OrGroupBuilder),

pub fn since_realtime(&mut self, usec: u64) -> &mut Self

pub fn until_realtime(&mut self, usec: u64) -> &mut Self

pub fn after_cursor(&mut self, cursor: Cursor) -> &mut Self

pub fn seek_head(&mut self) -> &mut Self

Seek to the start of the journal (oldest entries).

This clears any cursor-based starting position and disables reverse.

pub fn seek_tail(&mut self) -> &mut Self

Seek to the end of the journal (newest entries).

This clears any cursor-based starting position and enables reverse.

pub fn reverse(&mut self, reverse: bool) -> &mut Self

pub fn limit(&mut self, n: usize) -> &mut Self

pub fn iter(&self) -> Result<impl Iterator<Item = Result<EntryRef>> + use<>>

pub fn collect_owned(&self) -> Result<Vec<EntryOwned>>

pub fn follow(&self) -> Result<Follow>

Trait Implementations

impl Clone for JournalQuery

fn clone(&self) -> JournalQuery

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
