pub struct Params(pub Vec<Param>);
Expand description
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");
- by the index of the parameter. This way you can also get the name (key)
let third_key = ¶ms[2].key; let third_value = ¶ms[2].value;
Returns the value of the first Param
whose key matches the given name.

This method tests for self
and other
values to be equal, and is used
by ==
.
This method tests for !=
. The default implementation is almost always
sufficient, and should not be overridden without very good reason.
