Enum IpcError 

pub enum IpcError {
    Io(Error),
    Codec(Error),
    Unauthorized(String),
    UnsupportedPlatform,
}

Errors raised while framing, transporting, or authenticating IPC messages.

PRODUCT.md A.3/A.4: transport + peer-credential failures are distinct from application-level failures (which travel in-band as IpcResponse::Err).

Variants

Io(Error)

Underlying socket / framing I/O failed.

Codec(Error)

A frame could not be (de)serialized to/from JSON.

Unauthorized(String)

The connecting peer failed the SO_PEERCRED/LOCAL_PEERCRED check (PRODUCT.md A.3 - uid/pid not in the allowed set).

UnsupportedPlatform

Peer-credential introspection is not implemented for this OS.

Trait Implementations

impl Debug for IpcError

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

Formats the value using the given formatter.

impl Display for IpcError

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

impl Error for IpcError

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.
