Struct rustc_query_system::dep_graph::SerializedDepGraph

pub struct SerializedDepGraph {
    nodes: IndexVec<SerializedDepNodeIndex, DepNode>,
    fingerprints: IndexVec<SerializedDepNodeIndex, Fingerprint>,
    edge_list_indices: IndexVec<SerializedDepNodeIndex, EdgeHeader>,
    edge_list_data: Vec<u8>,
    index: Vec<UnhashMap<PackedFingerprint, SerializedDepNodeIndex>>,
}

Data for use when recompiling the current crate.

Fields

nodes: IndexVec<SerializedDepNodeIndex, DepNode>

The set of all DepNodes in the graph

fingerprints: IndexVec<SerializedDepNodeIndex, Fingerprint>

The set of all Fingerprints in the graph. Each Fingerprint corresponds to the DepNode at the same index in the nodes vector.

edge_list_indices: IndexVec<SerializedDepNodeIndex, EdgeHeader>

For each DepNode, stores the list of edges originating from that DepNode. Encoded as a [start, end) pair indexing into edge_list_data, which holds the actual DepNodeIndices of the target nodes.

edge_list_data: Vec<u8>

A flattened list of all edge targets in the graph, stored in the same varint encoding that we use on disk. Edge sources are implicit in edge_list_indices.

index: Vec<UnhashMap<PackedFingerprint, SerializedDepNodeIndex>>

Stores a map from fingerprints to nodes per dep node kind. This is the reciprocal of nodes.

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.
