//! Typed errors for the bob SDK.

/// Why a bob-rs operation (install, keychain I/O, spawn) failed.
///
/// Each variant carries the real underlying error as a source — an
/// [`std::io::Error`], a [`keyring::Error`], a [`serde_json::Error`], or a
/// [`cli_stream::StreamError`] — rather than a pre-formatted string, so a
/// consumer can inspect or downcast it (e.g. branch on `io::ErrorKind`, or
/// recognise a `keyring::Error::NoEntry`). `#[non_exhaustive]` so adding a
/// variant later isn't a breaking change.
#[derive(Debug, thiserror::Error)]
#[non_exhaustive]
pub enum BobError {
    /// An OS-level I/O failure while running the installer — spooling the
    /// embedded script to a tempfile, setting its mode, spawning `bash`, or
    /// waiting on it. `context` names the step; `source` is the OS error.
