A standalone Eclipse IDE for Rust Developers is also available for download here.
Corrosion provides a rich editor with:

• Error reporting
• Hover
• Content assist
• Jump to references
• Code Outline
• Formatting
• Syntax highlighting (using TextMate grammar)
• And even more, provided by the Rust Language Server
  It also integrates various operations of the cargo command-line (New, Build, Run, Debug, Package) as typical Eclipse IDE wizards and workflows.
