Class SuboptimalCellOperation

A detector that highlights Cell operations that could be optimized with more gas-effective calls.

Why is it bad?

There are several methods in the stdlib structures that provide a more efficient API for the intended logic.

Currently, this detector suggests:

  • Replacing load* with skip* when the result is unused.

Example

fun test(s: Slice) {
  s.loadInt(8); // Bad: result is unused
}

Use instead:

fun test(s: Slice) {
  s.skipBits(8); // OK
}

Accessors

id

  • get id(): string

  • Gets the short identifier of the detector, used in analyzer warnings.

    Returns string

    The unique identifier of the detector.

kind

shareImportedWarnings

  • get shareImportedWarnings(): WarningsBehavior

  • Defines the behavior of warnings generated by this detector when working with multiple projects within a single Tact configuration.

    Here are the available options:

    1. "union" Leave this value if you don't care about warnings generated in other projects.
    2. "intersect" If the warning is generated for some source location of the imported file, it should be generated by each of the projects. Example: Constants from an imported file should not be reported iff they are unused in all the projects, so you need "intersect".

    Returns WarningsBehavior

usesSouffle

  • get usesSouffle(): boolean

  • Checks whether this detector needs the Soufflé binary to be executed.

    Returns boolean
