Struct rustc_trait_selection::traits::select::ProvisionalEvaluation
source · [−]struct ProvisionalEvaluation {
from_dfn: usize,
reached_depth: usize,
result: EvaluationResult,
dep_node: DepNodeIndex,
}Expand description
A cache value for the provisional cache: contains the depth-first number (DFN) and result.
Fields
from_dfn: usizereached_depth: usizeresult: EvaluationResultdep_node: DepNodeIndexThe DepNodeIndex created for the evaluate_stack call for this provisional
evaluation. When we create an entry in the evaluation cache using this provisional
cache entry (see on_completion), we use this dep_node to ensure that future reads from
the cache will have all of the necessary incr comp dependencies tracked.

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
