Module Build 

Dynamic Build Orchestrator

This binary serves as a powerful, configurable pre-build step for a Tauri application. It is designed to be called from a shell script and dynamically modifies project configuration files (Cargo.toml, tauri.conf.json) based on environment variables and command-line arguments.

Its primary responsibilities include:

• Generating a unique productName and identifier for different build “flavours” (e.g., for different dependencies, environments, or feature sets).

• Dynamically selecting a sidecar binary (like a specific Node.js version),

  staging it in a temporary location, and configuring Tauri to bundle it.

• Temporarily modifying configuration files, executing the final build command (e.g., pnpm tauri build), and then restoring the original files using a Guard pattern.

Structs

Argument

Represents parsed command-line arguments and environment variables that control the build.

Guard

Manages the backup and restoration of a single file using the RAII pattern. Ensures that an original file is restored to its initial state when this struct goes out of scope.

Manifest

Represents the package section of a Cargo.toml manifest.

Meta

Represents metadata within the package section of Cargo.toml.

Enums

Error

Represents all possible errors that can occur during the build script’s execution.

Constants

BackupSuffix

Suffix used for backup files created by the Guard.

BrowserEnv

Environment variable for the “Browser” build flag.

BundleEnv

Environment variable for the “Bundle” build flag.

CargoFile

Cargo configuration filename.

CleanEnv

Environment variable for the “Clean” build flag.

CompileEnv

Environment variable for the “Compile” build flag.

DependencyEnv

Environment variable for specifying a dependency flavour.

DirEnv

Environment variable for the project directory.

LogEnv

Environment variable for setting the log level.

NameDefault

Default project base name, used as a suffix for generated names.

NameDelimiter

Delimiter for parts of the generated productName.

NameEnv

Environment variable for the original base name of the project.

Process

Main orchestration logic for preparing and executing the build.

TomlEdit

Dynamically modifies specific name fields within a Cargo.toml file. This includes package.name, package.default-run, and bin.name.
