Struct pavex::request::path::errors::InvalidUtf8InPathParam

#[non_exhaustive]
pub struct InvalidUtf8InPathParam { /* private fields */ }

One of the percent-decoded path parameters is not a valid UTF8 string.

URL parameters must be percent-encoded whenever they contain characters that are not URL safe—e.g. whitespaces.

Pavex automatically percent-decodes URL parameters before trying to deserialize them in PathParams<T>. This error is returned whenever the percent-decoding step fails—i.e. the decoded data is not a valid UTF8 string.

Example

One of our routes is /address/:address_id. We receive a request with /address/the%20street as path—address_id is set to the%20street and Pavex automatically decodes it into the street.

We could also receive a request using /address/dirty%DE~%C7%1FY as path—address_id, when decoded, is a sequence of bytes that cannot be interpreted as a well-formed UTF8 string. This error is then returned.
