# Functions

New constructs a new Graph.

# Constants

Precedence indicates that the source (from) of the edge must be reached before the destination (to), whether in a previous stage or the same stage.
PreviousStagePrecedence indicates that the source (from) of the edge must be reached before the destination (to), and _must_ do so in a previous stage.
PreviousTransactionPrecedence indicates that the source (from) of the edge must be reached before the destination (to), and _must_ do so in a previous transaction.
SameStagePrecedence indicates that the source (from) of the edge must be reached before the destination (to), and _must_ do so in the same stage.

# Structs

DepEdge represents a dependency between two nodes.
Graph is a graph whose nodes are *screl.Nodes.
OpEdge represents an edge changing the state of a target with an op.
Rule describes a reason for a DepEdge to exist.

# Interfaces

Edge represents a relationship between two Nodes.

# Type aliases
