Struct LogBufFile

pub struct LogBufFile {
    pub level: Level,
    pub format: LogFormat,
    pub file_path: Box<Path>,
    pub flush_millis: usize,
    pub rotation: Option<Rotation>,
}

Config for buffered file sink which merged I/O and delay flush

Fields

level: Level

max log level in this file

format: LogFormat

file_path: Box<Path>

path: dir/name

flush_millis: usize

default to 0, means always flush when no more message to write.

when larger than zero, will wait for new message when timeout occur.

rotation: Option<Rotation>

Rotation config

Implementations

impl LogBufFile

pub fn new<P1, P2>( dir: P1, file_name: P2, level: Level, format: LogFormat, flush_millis: usize, ) -> Self

where P1: Into<PathBuf>, P2: Into<PathBuf>,

Construct config for file sink with buffer.

Will try to create dir if not exists. Periodic flush if flush_millis is zero, or buffer size reaching 4096. will ensure a complete line write to the log file.

Arguments:

The type of dir and file_name can be &str / String / &OsStr / OsString / Path / PathBuf. They can be of different types.

• flush_millis:

  • default to 0, means always flush when no more message to write.

  • when larger than zero, will wait for new message when timeout occur. The max value is 1000 (1 sec).

pub fn rotation(self, ro: Rotation) -> Self

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.
