Enum access_json::QueryExecErr

pub enum QueryExecErr {
    EmptyQuery,
    InternalError(String),
    Serialization(String),
}

An enum representing a runtime error given a correctly-parsed query.

Variants

EmptyQuery

You gave us a query that has no fields or array accesses in it. Just call serde_json::to_value instead of going through the query API!

InternalError(String)

Basically a panic; please open a github issue, with data if possible!

Serialization(String)

Since we're currently implementing a serde Serializer to run the queries, we need a catch-all for custom errors, e.g., in user-specified serialization targets.

Trait Implementations

impl Debug for QueryExecErr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QueryExecErr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for QueryExecErr

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

Formats the value using the given formatter.

impl Eq for QueryExecErr

impl Error for QueryExecErr

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

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()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

impl Error for QueryExecErr

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

Used when a [Serialize] implementation encounters any error while serializing a type.

impl From<Error> for QueryExecErr

fn from(err: Error) -> Self

Performs the conversion.

impl PartialEq<QueryExecErr> for QueryExecErr

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for QueryExecErr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
