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 }} with value

Interact with this utility via the parse function

Examples

Basic usage:

```rust use std::collections::HashMap;

let mut vars = HashMap::new(); vars.insert( "key".toowned(), "value".toowned() );

assert_eq!( "value", varj::parse("{{ key }}", &vars)? ); ```

With a json string:

```rust let mut variables = varj::VarjMap::new(); variables.insert("name".toowned(), "Christopher".toowned()); variables.insert("age".toowned(), "30".toowned());

let json = r#"{ "name" = "{{ name }}", "age" = {{ age }} }"#;

let expected = r#"{ "name" = "Christopher", "age" = 30 }"#;

let actual = varj::parse(json, &variables)?;

assert_eq!(expected, actual); ```
