Enum QueryError 

pub enum QueryError {
    MissingQueryString,
    ParseError(String),
    DeserializationError(String),
}

Error types for query parameter extraction and deserialization.

This error type implements std::error::Error for integration with error handling libraries.

Variants

MissingQueryString

No query string found in the request URI.

ParseError(String)

Failed to parse query parameters from the query string.

DeserializationError(String)

Query parameter deserialization failed (type mismatch, missing field, etc.).

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Eq for QueryError

impl Error for QueryError

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 PartialEq for QueryError

fn eq(&self, other: &QueryError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Responder for QueryError

fn into_response(self) -> Response<TakoBody>

Converts query parameter errors into appropriate HTTP error responses.
