Function gtmpl::funcs::index [−][src]
pub fn index(args: &[Value]) -> Result<Value, FuncError>
Expand description
Returns the result of indexing its first argument by the following arguments. Thus “index x 1 2 3” is, in Go syntax, x[1][2][3]. Each indexed item must be a map, slice or array.
Example
use gtmpl::template; let ctx = vec![23, 42, 7]; let index = template("{{ index . 1 }}", ctx); assert_eq!(&index.unwrap(), "42");
