Struct cargo_metadata::diagnostic::DiagnosticSpanMacroExpansion

#[non_exhaustive]
pub struct DiagnosticSpanMacroExpansion {
    pub span: DiagnosticSpan,
    pub macro_decl_name: String,
    pub def_site_span: Option<DiagnosticSpan>,
}

Macro expansion information associated with a diagnostic.

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.

span: DiagnosticSpan

span where macro was applied to generate this code; note that this may itself derive from a macro (if span.expansion.is_some())

macro_decl_name: String

name of macro that was applied (e.g., “foo!” or “#[derive(Eq)]”)

def_site_span: Option<DiagnosticSpan>

span where macro was defined (if known)

Trait Implementations

impl Clone for DiagnosticSpanMacroExpansion

fn clone(&self) -> DiagnosticSpanMacroExpansion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DiagnosticSpanMacroExpansion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DiagnosticSpanMacroExpansion

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DiagnosticSpanMacroExpansion

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<DiagnosticSpanMacroExpansion> for DiagnosticSpanMacroExpansion

fn eq(&self, other: &DiagnosticSpanMacroExpansion) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DiagnosticSpanMacroExpansion

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

Serialize this value into the given Serde serializer.
