Struct RustcDiagnostic 

pub struct RustcDiagnostic {
    pub message: String,
    pub code: Option<RustcCode>,
    pub level: String,
    pub spans: Vec<RustcSpan>,
    pub children: Vec<RustcDiagnostic>,
    pub rendered: Option<String>,
}

A diagnostic message from rustc

Fields

message: String

The main error message

code: Option<RustcCode>

Optional error code (e.g., E0425)

level: String

Severity level: “error”, “warning”, “note”, “help”

spans: Vec<RustcSpan>

Source code spans where the error occurred

children: Vec<RustcDiagnostic>

Child diagnostics (notes, suggestions)

rendered: Option<String>

Rendered text output (optional)

Implementations

impl RustcDiagnostic

pub fn from_json(json: &str) -> Result<Self, Error>

Parse a rustc diagnostic from JSON string

pub fn from_json_lines(json_lines: &str) -> Result<Vec<Self>, Error>

Parse multiple diagnostics from JSON lines

pub fn primary_span(&self) -> Option<&RustcSpan>

Get the primary span (the main location of the error)

pub fn primary_position(&self) -> Option<(String, usize, usize)>

Get the primary position as (file, line, column)

pub fn is_error(&self) -> bool

Check if this is an error (vs warning or note)

pub fn is_warning(&self) -> bool

Check if this is a warning

Trait Implementations

impl Clone for RustcDiagnostic

fn clone(&self) -> RustcDiagnostic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RustcDiagnostic

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RustcDiagnostic

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RustcDiagnostic

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