Struct Diagnostic

#[non_exhaustive]
pub struct Diagnostic {
    pub message: String,

A diagnostic message generated by rustc

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

message: String

The error message of this diagnostic.

code: Option<DiagnosticCode>

The associated error code for this diagnostic

level: DiagnosticLevel

“error: internal compiler error”, “error”, “warning”, “note”, “help”

spans: Vec<DiagnosticSpan>

A list of source code spans this diagnostic is associated with.

children: Vec<Diagnostic>

Associated diagnostic messages.

rendered: Option<String>

The message as rustc would render it

Trait Implementations

impl Clone for Diagnostic

fn clone(&self) -> Diagnostic

Returns a copy 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 Display for Diagnostic

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

Formats the value using the given formatter.

impl Hash for Diagnostic

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.

impl Eq for Diagnostic

impl StructuralPartialEq for Diagnostic
