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

Why an I2C adapter could not be opened.

Variants

Unsupported

Adapter

The adapter’s device file could not be opened.

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 !=.
