    Nats(String),
    Ble(String),
    Llm(String),

}

Top-level application error for Gestura.

This error type encompasses common failure modes across the core library and domain crates, allowing for unified error handling across GUI and CLI.

Variants

Io(Error)

Generic I/O failure (file operations, etc.)

Json(Error)

JSON serialization/deserialization error

Toml(String)

TOML parsing/serialization error

Nats(String)

NATS messaging client error

Ble(String)

BLE-related failures for haptic device communication

Llm(String)

LLM-related failures (API errors, model not found, etc.)

ContextOverflow(String)

Context window overflow - request exceeds model’s context limit.

This is distinct from generic LLM errors because it requires specific recovery action (context compaction) rather than simple retry.

Http(Error)

HTTP client error (for API calls)

Voice(String)

Voice/STT processing error

Audio(String)

Audio capture/playback error

Config(String)

Configuration error (invalid settings, missing config, etc.)

Session(String)

Session management error

Mcp(String)

MCP (Model Context Protocol) error

PermissionDenied(String)

Permission denied error (for system operations)

NotFound(String)

Resource not found error

Timeout(String)

Timeout error

InvalidInput(String)

Invalid input or argument error

Internal(String)

Internal error (unexpected state, etc.)

Trait Implementations

impl Debug for AppError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AppError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AppError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
