Enum GraphQLError 

pub enum GraphQLError {
    SchemaGeneration(String),
    SchemaError(String),
    QueryExecution(String),
    InvalidFilter(String),
    TypeMapping(String),
    AuthenticationRequired,
    Database(String),
}

Errors that can occur during GraphQL operations.

Variants

SchemaGeneration(String)

The schema could not be built from the database’s metadata. A fault in the translation, not in the request: no query has been seen yet.

SchemaError(String)

The built schema was rejected, or a lookup into it failed.

QueryExecution(String)

The query parsed and resolving it failed.

InvalidFilter(String)

A where argument that does not describe a filter this server can express – an unknown operator, or an operand of the wrong shape.

TypeMapping(String)

A PostgreSQL type with no GraphQL equivalent to map it onto.

AuthenticationRequired

The field needs an identity and the request carried none.

Database(String)

PostgreSQL refused the query. Its message is carried verbatim.

Trait Implementations

impl Debug for GraphQLError

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

Formats the value using the given formatter.

impl Display for GraphQLError

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

Formats the value using the given formatter.

impl Error for GraphQLError

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.
