    MissingPathParams,
    MissingParam {
        name: String,
    },
    InvalidValue {
        name: String,

    },
}

Error returned when path extraction fails.

Variants

MissingPathParams

Path parameters not available in request extensions. This indicates a server configuration error (router not setting params).

MissingParam

A required parameter was not found.

Fields

name: String

The parameter name that was missing.

InvalidValue

Parameter value could not be converted to the expected type.

Fields

name: String

The parameter name.

value: String

The actual value that couldn’t be converted.

expected: &'static str

Description of the expected type.

message: String

Additional error details.

DeserializeError

Deserialization error (e.g., wrong number of parameters for tuple).

Fields

message: String

The error message.

Trait Implementations

impl Debug for PathExtractError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PathExtractError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for PathExtractError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl Error for PathExtractError

fn custom<T: Display>(msg: T) -> Self

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl IntoResponse for PathExtractError

fn into_response(self) -> Response

Convert into a response.
