Enum DiagnosticTag 

pub enum DiagnosticTag {
    Unnecessary,
    Deprecated,
}

An LSP-aligned diagnostic tag — a rendering hint editors apply on top of the severity. Serialized as the LSP DiagnosticTag NUMBER (1 / 2) so protocol clients forward it without a mapping table.

Variants

Unnecessary

Unused or unreachable code — editors render it faded/dimmed (LSP value 1).

Deprecated

Deprecated code — editors render it struck through (LSP value 2).

Trait Implementations

impl Clone for DiagnosticTag

fn clone(&self) -> DiagnosticTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DiagnosticTag

impl Debug for DiagnosticTag

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DiagnosticTag

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Eq for DiagnosticTag

impl PartialEq for DiagnosticTag

fn eq(&self, other: &DiagnosticTag) -> 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 DiagnosticTag

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
