[−][src]Crate varj
A string interpolation utility to replace Mustache like placeholders with stored variables.
- Works as an extremely lightweight template library
- Does not require template compilation
- Simply replaces
{{ key }}
withvalue
Interact with this utility via the parse
function
Examples
Basic usage:
use std::collections::HashMap; let mut vars = HashMap::new(); vars.insert( "key".to_owned(), "value".to_owned() ); assert_eq!( "value", varj::parse("{{ key }}", &vars)? );
With a json string:
let mut variables = varj::VarjMap::new(); variables.insert("name".to_owned(), "Christopher".to_owned()); variables.insert("age".to_owned(), "30".to_owned()); let json = r#"{ "name" = "{{ name }}", "age" = {{ age }} }"#; let expected = r#"{ "name" = "Christopher", "age" = 30 }"#; let actual = varj::parse(json, &variables)?; assert_eq!(expected, actual);
