Mojo package

io

Core I/O operations: console input/output, file handling, writing traits.

The io package provides fundamental input/output functionality for reading from and writing to various sources including the console, files, and custom streams. It defines the core traits for the I/O system (Writer and Writable) that enable formatted output across different backends, along with concrete implementations for file operations and standard streams.

Use this package for console interaction, file operations, implementing custom output formatting for your types, or building I/O abstractions. Most programs use print() and file operations from this package, while library authors implement Writable to enable their types to work with any Writer.

Modules

• ​file: Provides APIs to read and write files.
• ​file_descriptor: Higher level abstraction for file stream.
• ​io: Provides utilities for working with input/output.
• ​write: Establishes the contract between Writer and Writable types.
