Struct AttrFormat

pub struct AttrFormat { /* private fields */ }

Implementations

impl AttrFormat

pub fn new() -> AttrFormat

pub fn set_level_fmt<F>(&mut self, levelfmt: F)

where F: Fn(LEVEL) -> String + Send + Sync + 'static,

Exmaple

set_level_fmt(|level| {
    let s = match level {
        LEVEL::Trace => "[T]",
        LEVEL::Debug => "[D]",
        LEVEL::Info => "[I]",
        LEVEL::Warn => "[W]",
        LEVEL::Error => "[E]",
        LEVEL::Fatal => "[F]",
        LEVEL::Off => "",
    };
    s.to_string()
});

pub fn set_time_fmt<F>(&mut self, timefmt: F)

where F: Fn() -> (String, String, String) + Send + Sync + 'static,

• This function splits a date into three parts and returns a tuple (String, String, String).
• You can customize the data for these three parts.

Generally,

• the first part is the date in the format %Y-%m-%d,
• the second part is the time in the format %H:%M:%S,
• and the third part is the fractional seconds, such as 6f.

Example

set_time_fmt(|| {
    let now: DateTime<Local> = Local::now();
    (now.format("%Y-%m-%d").to_string(), now.format("%H:%M:%S").to_string(), ".6f".to_string())
});

pub fn set_body_fmt<F>(&mut self, bodyfmt: F)

where F: Fn(LEVEL, String) -> String + Send + Sync + 'static,

This function will support the reprocessing of log information

Example

fmt.set_body_fmt(|level,body| {
    match level {
        LEVEL::Trace =>  format!("{}{}{}","\x1b[34m" ,body,"\x1b[0m") , //blue
        LEVEL::Debug => format!("{}{}{}","\x1b[36m" ,body,"\x1b[0m") , //cyan
        LEVEL::Info => format!("{}{}{}","\x1b[32m" ,body,"\x1b[0m") ,  //green
        LEVEL::Warn => format!("{}{}{}","\x1b[33m" ,body,"\x1b[0m") ,  //yellow
        LEVEL::Error => format!("{}{}{}","\x1b[31m" ,body,"\x1b[0m") , //red
        LEVEL::Fatal => format!("{}{}{}","\x1b[41m" ,body,"\x1b[0m") , //red-background
        LEVEL::Off => "".to_string(),
    }
});
