Crate tracing_subscriber_multi 

tracing-subscriber-multi

Write tracing logs with helpful writer proxies, including:

• Writing to multiple places
• Writing to rotating log files
• Stripping ANSI sequences for a single writer

Example

use tracing_subscriber_multi::*;

let subscriber = FmtSubscriber::builder()
    .with_max_level(tracing::Level::TRACE)
    .with_ansi(true)
    .with_writer(std::sync::Mutex::new(DualWriter::new(
        std::io::stderr(),
        AnsiStripper::new(RotatingFile::new(
            "program.log",
            AppendCount::new(3),
            ContentLimit::Lines(1000),
            Compression::OnRotate(0),
        )),
    )))
    .finish();
tracing::subscriber::set_global_default(subscriber).expect("failed to initialise logger");

Structs

AnsiStripper

Strip ANSI control sequences.

AppendCount

Append a number when rotating the file. The greater the number, the older. The oldest files are deleted.

AppendTimestamp

Append current timestamp as suffix when rotating files. If the timestamp already exists, an additional number is appended.

DualWriter

A best-effort writer that supports multiple sub-writers.

FmtSubscriber

A Subscriber that logs formatted representations of tracing events.

QuadrupleWriter

A best-effort writer that supports multiple sub-writers.

QuintupleWriter

A best-effort writer that supports multiple sub-writers.

RotatingFile

A rotating log file. This will create log files that are limited in size, before being moved to name.X and optionally compressed.

TripleWriter

A best-effort writer that supports multiple sub-writers.

Enums

Compression

Compression mode - when to compress files.

ContentLimit

When to move files: Condition on which a file is rotated.
