Module rtlola_frontend::mir [−][src]
Expand description
This module covers the Mid-Level Intermediate Representation (MIR) of an RTLola specification.
The RtLolaMir is specifically designed to allow convenient navigation and access to data. Hence, it is perfect for working with the specification rather than work on it.
Most Notable Structs and Enums
- RtLolaMir is the root data structure representing the specification.
- OutputStream represents a single output stream. The data structure is enriched with information regarding streams accessing it or accessed by it and much more. For input streams confer InputStream.
- StreamReference used for referencing streams within the Mir.
- InstanceTemplate contains all information regarding the parametrization and spawning behavior of streams.
- Expression represents an expression. It contains its ExpressionKind and its type. The latter contains all information specific to a certain kind of expression such as sub-expressions of operators.
See Also
- rtlola_frontend for an overview regarding different representations.
- rtlola_frontend::parse to obtain an RtLolaMir for a specification in form of a string or path to a specification file.
- rtlola_hir::hir::RtLolaHir for a data structs designed for working _on_it.
- RtLolaAst, which is the most basic and down-to-syntax data structure available for RTLola.
Structs
This struct represents a single deadline inside a Schedule.
Represents an instance of a discrete window
Wrapper for output streams providing additional information specific to event-based streams.
Represents an expression
Contains all information inherent to an input stream.
Information on the spawn and parametrization behavior of a stream
Represents a layer indicating the position when an expression can be evaluated
Contains all information relevant to every kind of output stream.
This struct constitutes the Mid-Level Intermediate Representation (MIR) of an RTLola specification.
A schedule for the periodic streams.
Represents an instance of a sliding window
Information on the spawn behavior of a stream
Wrapper to collect the layer when a stream instance is spawned and evaluated
Wrapper for output streams providing additional information specific to time-driven streams.
Wrapper for output streams that are in-fact triggers. Provides additional information specific to triggers.
The size of a specific value in bytes.
Enums
Representation of the activation condition of event-based entities such as streams or spawn conditions
Arithmetical and logical operations
Represents a constant value of a certain kind.
This enum contains all possible kinds of expressions and their relevant information.
This enum indicates how much memory is required to store a stream.
Offset used in the lookup expression
Represents an RTLola pacing type.
Representation of the different stream accesses
Allows for referencing a stream within the specification.
This enum represents the different tasks that have to be executed periodically.
Represents an RTLola value type. This does not including pacing information, for this refer to TimeDrivenStream and EventDrivenStream.
The Ast representation of the different aggregation functions
Allows for referencing a window instance.
Traits
A trait for any kind of stream.
Type Definitions
Allows for referencing an input stream within the specification.
Allows for referencing an output stream within the specification.
A type alias for references to triggers.
