Struct JournalQuery 

pub struct JournalQuery<'a> {
    pub lines: u32,
    pub unit: Option<&'a str>,
    pub priority: Option<&'a str>,
    pub boot: bool,
    pub kernel: bool,
    pub since: Option<&'a str>,
    pub until: Option<&'a str>,
    pub grep: Option<&'a str>,
}

A validated journal query. All string fields are assumed to have passed the executor’s validators before reaching here.
