This is an accurate statement.
Could you say more about what the issue is? For example, "I'm trying to parse the string by splitting it apart at /
so I want to preserve the escape characters"?

(Thinking on it a little more, the fact that it's a wildcard segment and specifically the escape code for /
is what makes this different from all other cases, I guess.)

Yeah, that's it, the wildcard match is all delivered as one string and the app is responsible for splitting it into segments. There's other ways of approaching this – for example, a wildcard segment could instead handle the splitting before inserting into the params map, and then wildcard segments would be Vec<String>
or Box<[String]>
instead of just String
.
There is also another, very simple solution here: When you have this particular kind of wildcard route, simply parse the URL yourself. It is only a line or two to .strip_prefix("...")
from the path.
The current
ParamsMap
implementation always unescapes param values. This means that, in a wildcard match at the end of a URL, the app has no way of distinguishing a slash as a URL separator from a slash that was originally a "%2F".Example code:
