[−][src]Struct treemux::Params
A Vec
of Param
returned by a route match.
There are two ways to retrieve the value of a parameter:
- by the name of the parameter
let user = params.get("user"); // defined by :user or *user
- by the index of the parameter. This way you can also get the name (key)
let third_key = ¶ms[2].key; // the name of the 3rd parameter let third_value = ¶ms[2].value; // the value of the 3rd parameter
