新字符串模板

Rust的简单可定制字符串模板库。

本库受 string_template 启发。

用法

将以下内容添加到您的 Cargo.toml（或使用 cargo-add）

[dependencies]
new_string_template = "1.5"

包含2个数据点的示例（启用fail）

use new_string_template::template::Template;
use std::collections::HashMap;

fn main() {
    let templ_str = "Something {data1} be {data2}, and { not here }";
    let templ = Template::new(templ_str);
    let data = {
        let mut map = HashMap::new();
        map.insert("data1", "should");
        map.insert("data2", "here");
        map
    };

    let rendered = templ.render(&data).expect("Expected Result to be Ok");
    assert_eq!("Something should be here, and { not here }", rendered);
}

包含1个数据点的示例（禁用fail）

use new_string_template::template::Template;
use std::collections::HashMap;

fn main() {
    let templ_str = "Something {data1} be {data2}, and { not here }";
    let templ = Template::new(templ_str);
    let data = {
        let mut map = HashMap::new();
        map.insert("data1", "should");
        // map.insert("data2", "here");
        map
    };

    let rendered = templ.render_nofail(&data);
    assert_eq!("Something should be {data2}, and { not here }", rendered);
}

包含自定义正则表达式的示例

use new_string_template::template::Template;
use std::collections::HashMap;
use regex::Regex;

fn main() {
    // The following regex requires at least one space between "{{" and "}}" and allows variables with spaces
    let custom_regex = Regex::new(r"(?mi)\{\{\s+([^\}]+)\s+\}\}").unwrap();
    let templ_str = "Something {{ data1 }} be {{ data2 }}, and {{ data 3 }}";
    let templ = Template::new(templ_str).with_regex(&custom_regex);
    let data = {
        let mut map = HashMap::new();
        map.insert("data1", "should");
        map.insert("data2", "here");
        map.insert("data 3", "here too");
        map
    };

    let rendered = templ.render_nofail(&data);
    assert_eq!("Something should be here, and here too", rendered);
}

注意：使用默认正则表达式时，模板变量可以有空白或没有。
