Type Alias CommandResult 

pub type CommandResult = Result<()>;

Result type for Clawless commands

Commands in Clawless execute a piece of logic that might fail for various reasons. If such an error is unrecoverable during the execution of the command, it will cause the CLI to fail and exit with an error message.

To make it easier to handle errors when implementing commands, every command handler returns a CommandResult type. This makes it possible to use the question mark ? operator and return early when an unrecoverable error occurs.

The CommandResult is a type alias for anyhow::Result<()>, which provides a more ergonomic way to handle arbitrary errors. Since it isn’t possible to recover from the error, we do not need to provide a specific error type that a caller could handle gracefully. Similarly, commands do not need to return a value, thus the result is always Result<()>.

Aliased Type

pub enum CommandResult {
    Ok(()),
    Err(Error),
}
