Enum VerbosityOutput 

pub enum VerbosityOutput {
    Println,
    Log,
    File(String),
}

Output backend used by verbosity logging.

Default is Println to preserve current behavior.

Variants

Println

Emit messages with println!.

Typical usage:

use copp::diag::{VerbosityOutput, set_verbosity_output};

set_verbosity_output(VerbosityOutput::Println)?;

Log

Emit messages through the log facade (info/debug/trace).

Before selecting this mode, initialize a global logger in your app/test.

Typical usage:

use log::LevelFilter;
use std::sync::Once;
use copp::diag::{VerbosityOutput, set_verbosity_output};

static INIT: Once = Once::new();
INIT.call_once(|| {
    let _ = env_logger::Builder::new()
        .filter_level(LevelFilter::Info)
        .is_test(true)
        .try_init();
});
set_verbosity_output(VerbosityOutput::Log)?;

File(String)

Emit messages to a configured log file.

Typical usage:

use copp::diag::{VerbosityOutput, set_verbosity_output};

// Auto-creates parent directories and opens file in append mode.
set_verbosity_output(VerbosityOutput::File("logs/copp/run.log".into()))?;

Trait Implementations

impl Clone for VerbosityOutput

fn clone(&self) -> VerbosityOutput

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VerbosityOutput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VerbosityOutput

fn default() -> VerbosityOutput

Returns the “default value” for a type.

impl PartialEq for VerbosityOutput

fn eq(&self, other: &VerbosityOutput) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
