Trait strfmt::Format

pub trait Format {
    // Required methods
    fn format<K, D: DisplayStr>(&self, vars: &HashMap<K, D>) -> Result<String>
       where K: Hash + Eq + FromStr;
    fn format_display<K, D: Display>(
        &self,
        vars: &HashMap<K, D>
    ) -> Result<String>
       where K: Hash + Eq + FromStr;
}

This trait is a shortcut for [strfmt] for an example see Format::format

Required Methods

fn format<K, D: DisplayStr>(&self, vars: &HashMap<K, D>) -> Result<String>where K: Hash + Eq + FromStr,

format a string using strfmt

Arguments

• vars - A HashMap holding the variables to use

Errors

Errors are passed directly from strfmt, for details see [strfmt]

Examples

use std::collections::HashMap;
use std::f64::consts::PI;
use strfmt::Format;

let mut my_vars: HashMap<String, f64> = HashMap::new();
my_vars.insert("Alpha".to_string(),42.0);
my_vars.insert("Beta".to_string(),PI);

println!("{}", "|{Alpha}|{Beta:<5.2}|".format(&my_vars).unwrap());

fn format_display<K, D: Display>(&self, vars: &HashMap<K, D>) -> Result<String>where K: Hash + Eq + FromStr,

👎Deprecated since 0.2.0: This function contains a bug when formatting numbers. Use format instead

format a string using strfmt_display see Format::format for usage
