Module brane_ast::ast

Defines the brane-ast AST, which is defined as an acyclic* graph where the nodes are external, orchestratable and policy-sensitive tasks (e.g., compute tasks or transfer tasks), and the edges are ‘control flow’ that are small pieces of BraneScript that decide which task to compute next. Can be thought of as a graph with intelligent edges.

Structs

• ClassDef
  Defines a class that is referenced in the edges.
• ComputeTaskDef
  Defines the contents of a compute task.
• FunctionDef
  Defines a function that is referenced in the edges.
• MAIN_FUNC
  A static FunctionDef for main.
• Metadata
  Defines a piece of metadata.
• SymTable
  Defines the SymTable, which is like a symbol table (very much so, even) but now specific to Workflowland.
• TRANSFER_FUNC
  A static FunctionDef for the Transfer.
• VarDef
  Defines a variable that is referenced in the edges.
• Workflow
  Defines a Workflow, which is meant to be an ‘executable but reasonable’ graph.

Enums

• Edge
  Defines an Edge (i.e., an intelligent control-flow operation) in the Workflow graph.
• EdgeInstr
  Defines an instruction for use within edges, which performs some computation in BraneScriptland (i.e., the edges).
• TaskDef
  Defines a Task (i.e., a Node) in the Workflow graph.
