Trait Implementations

impl DepNodeExt for DepNode

fn from_def_path_hash(
    tcx: TyCtxt<'_>,
    def_path_hash: DefPathHash,
    kind: DepKind
) -> DepNode

Construct a DepNode from the given DepKind and DefPathHash. This method will assert that the given DepKind actually requires a single DefId/DefPathHash parameter.

fn extract_def_id<'tcx>(&self, tcx: TyCtxt<'tcx>) -> Option<DefId>

Extracts the DefId corresponding to this DepNode. This will work if two conditions are met:

1. The Fingerprint of the DepNode actually is a DefPathHash, and
2. the item that the DefPath refers to exists in the current tcx.

Condition (1) is determined by the DepKind variant of the DepNode. Condition (2) might not be fulfilled if a DepNode refers to something from the previous compilation session that has been removed.

fn from_label_string(
    tcx: TyCtxt<'_>,
    label: &str,
    def_path_hash: DefPathHash
) -> Result<DepNode, ()>

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.
