Struct Log 

pub struct Log {
    header: Vec<String>,
    entries: Vec<Entry>,
    clock: fn() -> i64,
    path: Option<PathBuf>,
    file: Option<File>,
}

Fields

header: Vec<String>

entries: Vec<Entry>

clock: fn() -> i64

path: Option<PathBuf>

file: Option<File>

Implementations

impl Log

pub fn create(header: Vec<String>, path: Option<PathBuf>) -> Log

header heads the file and not the pane: it is what support asks for first, which a user reading along does not need. A file that cannot be opened leaves a log without one.

pub fn with_clock( header: Vec<String>, path: Option<PathBuf>, clock: fn() -> i64, ) -> Log

create, telling the time by clock, so a test can name the moment.

pub fn attach(&mut self, path: PathBuf)

Points the log at a file, writing out the header and everything said so far, since the game folder it belongs in is only known partway through the run; a second call follows the run to another folder.

pub fn line(&mut self, text: impl Into<String>)

Flushed at once, so a run that dies still leaves the line saying what it was doing.

pub fn lines(&self) -> impl Iterator<Item = &str>

As the pane shows them: without the times, which only the file needs.

pub fn text(&self) -> String

CRLF-separated, because a Win32 multiline edit ignores a lone LF.

pub fn path(&self) -> Option<&Path>

None when no file was written, so the summary never points at one that does not exist.

pub fn is_empty(&self) -> bool
