Enum DirectiveResult 

#[non_exhaustive]
pub enum DirectiveResult {
    Include,
    Skip,
    Transform(Value),
    Error(String),
}

Result of custom directive evaluation.

Determines how a field should be handled after directive processing.

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.

Include

Include the field in the response (default behavior).

Skip

Skip the field entirely (like @skip(if: true)).

Transform(Value)

Transform the field value before returning. The transformation is applied after field resolution.

Error(String)

Directive encountered an error that should be reported.

Trait Implementations

impl Clone for DirectiveResult

fn clone(&self) -> DirectiveResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DirectiveResult

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

Formats the value using the given formatter.

impl Default for DirectiveResult

fn default() -> DirectiveResult

Returns the “default value” for a type.

impl Eq for DirectiveResult

impl PartialEq for DirectiveResult

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
