Struct rustc_query_system::query::QueryStackFrame

pub struct QueryStackFrame<D: DepKind> {
    pub description: String,
    span: Option<Span>,
    pub def_id: Option<DefId>,
    pub def_kind: Option<DefKind>,
    pub ty_adt_id: Option<DefId>,
    pub dep_kind: D,
}

Description of a frame in the query stack.

This is mostly used in case of cycles for error reporting.

Fields

description: String

span: Option<Span>

def_id: Option<DefId>

def_kind: Option<DefKind>

ty_adt_id: Option<DefId>

dep_kind: D

Implementations

impl<D: DepKind> QueryStackFrame<D>

pub fn new( description: String, span: Option<Span>, def_id: Option<DefId>, def_kind: Option<DefKind>, dep_kind: D, ty_adt_id: Option<DefId>, _hash: impl FnOnce() -> Hash64 ) -> Self

pub fn default_span(&self, span: Span) -> Span

Trait Implementations

impl<D: Clone + DepKind> Clone for QueryStackFrame<D>

fn clone(&self) -> QueryStackFrame<D>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<D: Debug + DepKind> Debug for QueryStackFrame<D>

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

Formats the value using the given formatter.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
