Function redirect_stderr

pub fn redirect_stderr(
    buffer: BufferId,
    tag: &str,
    prio: Priority,
) -> Result<()>

Open an unstructured connection to a DLog logging sink.

Opens a connection with stderr to which you can stream data. DLog will automatically convert it to individual logs appropriately.

Arguments

• buffer - Target DLog buffer.
• tag - DLog tag for the resulting logs.
• prio - Priority for the resulting logs.

Errors

• std::io::ErrorKind::InvalidInput - Buffer does not allow connections.
• std::io::ErrorKind::PermissionDenied - Buffer disabled via dlog config.
• std::io::ErrorKind::Uncategorized - Buffer not configured via dlog config.
• std::io::ErrorKind::Uncategorized - Unsupported DLog backend.
• std::io::ErrorKind::InvalidInput - Tag empty.

Examples

use dlog::{BufferId, Priority};
use dlog_redirect_stdout::redirect_stderr;

fn main() -> Result<(), std::io::Error> {
    redirect_stderr(BufferId::LogIdMain, "foo", Priority::Info)?;
    // The following sends an info log with tag "foo" and message "my_message".
    eprintln!("my_message");
    Ok(())
}
