Module dfir_lang::graph::ops

Hydroflow’s operators

Structs

• OperatorConstraints
  An instance of this struct represents a single dfir operator.
• OperatorWriteOutput
  The code generated and returned by a OperatorConstraints::write_fn.
• WriteContextArgs
  Context arguments provided to OperatorConstraints::write_fn.

Enums

• DelayType
  The delay (soft barrier) type, for each input to an operator if needed.
• FloType
  Operator type for Flo semantics.
• OperatorCategory
  Operator categories, for docs.
• Persistence
  Persistence lifetimes: 'tick, 'static, or 'mutable.
• PortListSpec
  Specification of the named (or unnamed) ports for an operator’s inputs or outputs.

Constants

• IDENTITY_WRITE_FN
  OperatorConstraints::write_fn for unary identity operators.
• NULL_WRITE_FN
  OperatorConstraints::write_fn for the null operator - an operator that ignores all inputs and produces no output.
• OPERATORS
  All Hydroflow operators.
• RANGE_0
  Convenience range: exactly zero.
• RANGE_1
  Convenience range: exactly one.
• RANGE_ANY
  Convenience range: zero or more (any number).

Traits

• RangeTrait
  An object-safe version of RangeBounds.

Functions

• find_node_op_constraints
  Find an operator by GraphNode.
• find_op_op_constraints
  Find an operator by an AST Operator.
• identity_write_iterator_fn
  Helper to write the write_iterator portion of OperatorConstraints::write_fn output for unary identity operators.
• null_write_iterator_fn
  Helper to write the write_iterator portion of OperatorConstraints::write_fn output for the null operator - an operator that ignores all inputs and produces no output.
• operator_lookup
  Get the operator lookup table, generating it if needed.

Type Aliases

• WriteFn
  Type alias for OperatorConstraints::write_fn’s type.
