Function set_minimum_priority

pub fn set_minimum_priority(prio: Priority) -> Result<()>

Blocks low priority logs.

Allows filtering low priority logs globally, think a runtime “–verbose” mode, except you can choose which priorities to filter. Using this (as opposed to filtering later, when retrieving logs) is that it helps conserve system logging resources (buffer space etc.).

Arguments

• prio - Minimum priority level.

Examples

use dlog::Priority;
use log::{error, info, warn};

fn main() -> Result<(), std::io::Error> {
    dlog::init(false)?;
    info!("no filter so this log goes through");
    dlog::set_minimum_priority(Priority::Warn)?;
    info!("WARN is a higher level than INFO so this log gets filtered");
    warn!("but this one still goes through");
    error!("as does this one");
    Ok(())
}
