Struct StripAnsiWriter 

pub struct StripAnsiWriter<W> { /* private fields */ }

A writer wrapper that strips ANSI escape codes from all output.

This is used for file logging to ensure clean output even when stdout layers use ANSI colors. Due to how tracing_subscriber shares span field formatting between layers, ANSI codes from one layer can leak into others. This wrapper strips those codes at write time.

Uses a zero-copy fast path when no ANSI codes are present. Thread-safe via internal Mutex.

Example

use tauri_plugin_tracing::StripAnsiWriter;
use tauri_plugin_tracing::tracing_appender::non_blocking;
use tauri_plugin_tracing::tracing_subscriber::{fmt, layer::SubscriberExt, util::SubscriberInitExt};

let file_appender = tracing_appender::rolling::daily("/tmp/logs", "app.log");
let (non_blocking, _guard) = non_blocking(file_appender);

tracing_subscriber::registry()
    .with(fmt::layer())  // stdout with ANSI
    .with(fmt::layer().with_writer(StripAnsiWriter::new(non_blocking)).with_ansi(false))
    .init();
