Enum SavedState 

pub enum SavedState {
    Working,
    Stored,
}

Identifier values for the saved state of some data / files.

Most “identifier” types in this module use a series of alphanumeric characters to identify an instance in the same manner that the Octatrack uses, e.g. TrackId::One or BankId::A

This SavedState “identifier” type is different. It will never be used with id*() methods to access the members of a collection. It is used in two locations to model Octatrack behaviour:

• Accessing the saved or unsaved set of Parts within a BankFile via the parts() method.
• Identifying which ProjectFile, BankFile, ArrangementFile or MarkersFile should be read from / written to.

Variants

Working

*.work files – working copy

Note on File Creates/Writes

Whole Project

Data is written to all *.work files when either a SYNC TO CARD or a SAVE PROJECT operation is executed from the Octatrack’s Project menu.

Save Bank

Data is written to bank<ID>.work file each time the SAVE BANK operation is executed from the Octatrack’s Project menu.

Save Arrangement

Data is written to arr<ID>.work file when the SAVE ARRANGEMENT operation is executed from the Octatrack’s Arranger sub-menu.

Stored

*.strd files – restorable, stored copy.

Note on File Creates/Writes

Whole Project

Data is written to new *.strd files on the first SAVE PROJECT operation from the Octatrack’s project menu. Subsequent SAVE PROJECT operations then save to those same files.

Save Bank

A bank<ID>.strd file is created when the SAVE BANK operation is first executed from the Octatrack’s Project menu. Data is written to the bank<ID>.strd file each time the SAVE BANK operation is executed from the Octatrack’s Project menu.

Save Arrangement

A arr<ID>.strd file is created when the SAVE ARRANGEMENT operation is first executed from the Octatrack’s Arranger sub-menu. Data is written to the arr<ID>.strd file each time the SAVE ARRANGEMENT operation is executed from the Octatrack’s Arranger sub-menu.
