Struct GraphQLErrorNote 

pub struct GraphQLErrorNote {
    pub kind: GraphQLErrorNoteKind,
    pub message: String,
    pub span: Option<SourceSpan>,
}

An error note providing additional context about an error.

Notes augment the primary error message with:

• Explanatory context (why the error occurred)
• Actionable suggestions (how to fix it)
• Specification references (where to learn more)
• Related source locations (e.g., where a delimiter was opened)

Fields

kind: GraphQLErrorNoteKind

The kind of note (determines rendering prefix).

message: String

The note message.

span: Option<SourceSpan>

Optional pre-resolved span pointing to a related location.

When present, the note is rendered with a source snippet pointing to this location. Like the primary error’s source_span, this is eagerly resolved at error construction time so it carries line/column/byte-offset information without requiring a SourceMap at display time.

Implementations

impl GraphQLErrorNote

pub fn general(message: impl Into<String>) -> Self

Creates a general note without a span.

pub fn general_with_span(message: impl Into<String>, span: SourceSpan) -> Self

Creates a general note with a pre-resolved span.

pub fn help(message: impl Into<String>) -> Self

Creates a help note without a span.

pub fn help_with_span(message: impl Into<String>, span: SourceSpan) -> Self

Creates a help note with a pre-resolved span.

pub fn spec(url: impl Into<String>) -> Self

Creates a spec reference note.

Trait Implementations

impl Clone for GraphQLErrorNote

fn clone(&self) -> GraphQLErrorNote

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphQLErrorNote

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

Formats the value using the given formatter.

impl PartialEq for GraphQLErrorNote

fn eq(&self, other: &GraphQLErrorNote) -> 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.
