Enum ComplexityValidationError 

#[non_exhaustive]
pub enum ComplexityValidationError {
    QueryTooDeep {
        max_depth: usize,
        actual_depth: usize,
    },
    QueryTooComplex {

}

GraphQL query validation error types (depth, complexity, aliases).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

QueryTooDeep

Query exceeds maximum allowed depth.

Fields

max_depth: usize

Maximum allowed depth

actual_depth: usize

Actual query depth

QueryTooComplex

Query exceeds maximum complexity score.

Fields

max_complexity: usize

Maximum allowed complexity

actual_complexity: usize

Actual query complexity

TooManyAliases

Query contains too many aliases (alias amplification attack).

Fields

max_aliases: usize

Maximum allowed alias count

actual_aliases: usize

Actual alias count

InvalidVariables(String)

Invalid query variables.

MalformedQuery(String)

Malformed GraphQL query.

Trait Implementations

impl Clone for ComplexityValidationError

fn clone(&self) -> ComplexityValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ComplexityValidationError

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

Formats the value using the given formatter.

impl Display for ComplexityValidationError

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

Formats the value using the given formatter.

impl Error for ComplexityValidationError

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.
