Struct salsa_2022::runtime::local_state::QueryEdges

pub struct QueryEdges {
    pub input_outputs: Arc<[(EdgeKind, DependencyIndex)]>,
}

The edges between a memoized value and other queries in the dependency graph. These edges include both dependency edges e.g., when creating the memoized value for Q0 executed another function Q1) and output edges (e.g., when Q0 specified the value for another query Q2).

Fields

input_outputs: Arc<[(EdgeKind, DependencyIndex)]>

The list of outgoing edges from this node. This list combines both inputs and outputs.

Note that we always track input dependencies even when there are untracked reads. Untracked reads mean that we can’t verify values, so we don’t use the list of inputs for that, but we still use it for finding the transitive inputs to an accumulator.

You can access the input/output list via the methods [inputs] and [outputs] respectively.

Important:

• The inputs must be in execution order for the red-green algorithm to work.
