Enum Target 

pub enum Target {
    Stdout,
    Stderr,
    Webview,
    LogDir {
        file_name: Option<String>,
    },
    Folder {
        path: PathBuf,
        file_name: Option<String>,
    },
}

Specifies a log output destination.

Use these variants to configure where logs should be written. Multiple targets can be combined using Builder::target() or Builder::targets().

Example

use tauri_plugin_tracing::{Builder, Target};

// Log to stdout and webview (default behavior)
Builder::new()
    .targets([Target::Stdout, Target::Webview])
    .build::<tauri::Wry>();

// Log to file and webview only (no console)
Builder::new()
    .targets([
        Target::LogDir { file_name: None },
        Target::Webview,
    ])
    .build::<tauri::Wry>();

// Log to stderr instead of stdout
Builder::new()
    .clear_targets()
    .target(Target::Stderr)
    .target(Target::Webview)
    .build::<tauri::Wry>();

Variants

Stdout

Print logs to stdout.

Stderr

Print logs to stderr.

Webview

Forward logs to the webview via the tracing://log event.

This allows JavaScript code to receive logs using attachLogger() or attachConsole().

LogDir

Write logs to the platform-standard log directory.

Platform log directories:

• macOS: ~/Library/Logs/{bundle_identifier}
• Linux: ~/.local/share/{bundle_identifier}/logs
• Windows: %LOCALAPPDATA%/{bundle_identifier}/logs

The file_name parameter sets the log file prefix. Defaults to "app" if None, producing files like app.2024-01-15.log.

Fields

file_name: Option<String>

The log file prefix. Defaults to "app" if None.

Folder

Write logs to a custom directory.

The file_name parameter sets the log file prefix. Defaults to "app" if None, producing files like app.2024-01-15.log.

Fields

path: PathBuf

The directory path to write log files to.

file_name: Option<String>

The log file prefix. Defaults to "app" if None.
