Struct Diagnostic 

pub struct Diagnostic {
    pub range: TextRange,
    pub severity: Severity,
    pub code: String,
    pub message: String,
    pub source: DiagnosticSource,
    pub fixes: Vec<CodeAction>,
    pub tags: Vec<DiagnosticTag>,
}

A diagnostic with a byte range, a stable machine code, a severity, and a message.

Fields

range: TextRange

The byte range the diagnostic applies to.

severity: Severity

Severity.

code: String

A stable code, e.g. GDSCRIPT_SYNTAX or INTEGER_DIVISION.

message: String

Human-readable message.

source: DiagnosticSource

Which analysis layer produced it. Defaults to DiagnosticSource::Syntax so older serialized diagnostics and Phase-1 call sites round-trip unchanged.

fixes: Vec<CodeAction>

Quick-fixes offered for this diagnostic (e.g. “add type annotation”). Empty when none.

tags: Vec<DiagnosticTag>

LSP-aligned rendering tags (DiagnosticTag) — Unnecessary on the unused/unreachable family so editors dim it. Omitted from JSON when empty, so pre-tag serialized diagnostics and consumers round-trip unchanged.

Trait Implementations

impl Clone for Diagnostic

fn clone(&self) -> Diagnostic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Diagnostic

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Diagnostic

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Diagnostic

impl PartialEq for Diagnostic

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

impl Serialize for Diagnostic

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
