Enum OpenError 

pub enum OpenError {
    Unsupported,
    Device {
        path: PathBuf,
        reason: String,
    },
}

Why a serial device could not be opened.

Variants

Unsupported

This platform has no serial device this crate opens, or this build left out the linux feature that opens one.

Device

The device file could not be opened or set up as a raw byte pipe.

Fields

path: PathBuf

The device file.

reason: String

Why, in the kernel’s words.

impl Eq for OpenError

impl Error for OpenError

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 PartialEq for OpenError

fn eq(&self, other: &OpenError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
