Struct PluginDiagnostic 

pub struct PluginDiagnostic<'db> {
    pub stable_ptr: SyntaxStablePtrId<'db>,
    pub message: String,
    pub severity: Severity,
    pub inner_span: Option<(TextWidth, TextWidth)>,
}

A diagnostic generated by a plugin.

Fields

stable_ptr: SyntaxStablePtrId<'db>

The stable pointer of the syntax node that caused the diagnostic.

message: String

severity: Severity

The severity of the diagnostic.

inner_span: Option<(TextWidth, TextWidth)>

An optional inner span inside the stable pointer that caused the diagnostic. Useful for diagnostics caused by inline macros, since the syntax of the arguments is a token tree and is not segmented into each argument. The tuple is (offset, width).

Implementations

impl<'db> PluginDiagnostic<'db>

pub fn error( stable_ptr: impl Into<SyntaxStablePtrId<'db>>, message: String, ) -> PluginDiagnostic<'db>

pub fn error_with_inner_span( db: &dyn Database, stable_ptr: impl Into<SyntaxStablePtrId<'db>>, inner_span: SyntaxNode<'_>, message: String, ) -> PluginDiagnostic<'db>

Creates a diagnostic, pointing to an inner span inside the given stable pointer.

pub fn warning( stable_ptr: impl Into<SyntaxStablePtrId<'db>>, message: String, ) -> PluginDiagnostic<'db>

Trait Implementations

impl<'db> Clone for PluginDiagnostic<'db>

fn clone(&self) -> PluginDiagnostic<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for PluginDiagnostic<'db>

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

Formats the value using the given formatter.

impl<'db> Hash for PluginDiagnostic<'db>

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<'db> PartialEq for PluginDiagnostic<'db>

fn eq(&self, other: &PluginDiagnostic<'db>) -> 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<'db> Update for PluginDiagnostic<'db>

unsafe fn maybe_update(old_pointer_: *mut Self, new_value_: Self) -> bool

Returns

impl<'db> Eq for PluginDiagnostic<'db>

impl<'db> StructuralPartialEq for PluginDiagnostic<'db>
