Detailed Description

Defines all fundamental FlatImage paths.

Organizes paths into three categories: directories, files, and binaries. All paths are computed from the binary location and process ID.

FlatImage uses the following directory structure

/tmp/fim/                                    (global)
├── app/
│   └── {COMMIT}_{TIMESTAMP}/               (app)

Member Function Documentation

create()

static Value< Path > ns_config::Path::create ( )

inlinestatic

Factory method to create Path configuration.

Orchestrates initialization in the correct dependency order:

1. Dir::create() - Computes and creates directory structure
2. File::create() - Creates file paths based on instance directory
3. Bin::create() - Creates binary paths based on app_bin directory

Returns

Value<Path> Initialized path configuration or error
