Struct Journal 

pub struct Journal {
    pub id: String,
    pub path: PathBuf,
    pub executor: Option<&'static str>,
    pub assumptions: Option<Vec<&'static str>>,
    /* private fields */
}

Fields

id: String

path: PathBuf

executor: Option<&'static str>

Which ran the program, vm or interpreter, for the close record.

assumptions: Option<Vec<&'static str>>

The ids of the register’s assumptions the run could have rested on, in byte order, for the close record; None for a command that ran no program.

Implementations

impl Journal

pub fn create( dir: &Path, reads: &[PathBuf], command: &str, argv: &[String], tool_version: &str, ) -> Result<Journal, Error>

pub fn tip(&self) -> &str

The hash of the last record written.

pub fn append( &mut self, kind: &str, fields: BTreeMap<String, Value>, ) -> Result<(), Error>

pub fn close(self, exit: Option<i64>) -> Result<Ledger, Error>

Writes close, then the ledger record carrying this journal’s tip.
