Enum HostError 

pub enum HostError {
    BinaryMissing(PathBuf),
    ResolveFailed(String),
    HostGone,
    Io(Error),
    Protocol(String),
}

Why a resident-host capture could not be produced. Every variant means “fall back to simctl”, but they are distinguished for diagnostics.

Variants

BinaryMissing(PathBuf)

The smix-capture-host binary was not found on disk.

ResolveFailed(String)

The host was spawned but never emitted its WxH geometry header (surface resolve failed, or it crashed on launch).

HostGone

The host process died mid-conversation (stdout EOF on a grab).

Io(Error)

An I/O error talking to the host.

Protocol(String)

The host sent a malformed response header.

Trait Implementations

impl Debug for HostError

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

Formats the value using the given formatter.

impl Display for HostError

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

Formats the value using the given formatter.

impl Error for HostError

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.

impl From<Error> for HostError

fn from(e: Error) -> Self

Converts to this type from the input type.
