Enum OpenError 

pub enum OpenError {
    Unsupported,
    Gpio {
        chip: PathBuf,
        line: u32,
        reason: String,
    },
}

Why a line could not be opened.

Variants

Unsupported

The platform has no GPIO character device, which is any platform but Linux.

Gpio

The chip or the line could not be opened.

Fields

chip: PathBuf

The chip’s device file.

line: u32

The line’s number on it.

reason: String

Why, which is most often a missing chip, a line number past the chip’s last, a line another program holds, or a user outside the gpio group.

Trait Implementations

impl Clone for OpenError

fn clone(&self) -> OpenError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OpenError

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

Formats the value using the given formatter.

impl Display for OpenError

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

Formats the value using the given formatter.

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 !=.
