Struct apigpio::PigpiodError

pub struct PigpiodError(pub i32);

Wraps up a pigpiod error code

This is not an enum because if pigpiod is newer than apigpio, pigpiod might send error codes that apigpio does not understand. Specific error values can be checked for by comparing with values from the errors module.

Methods

impl PigpiodError

pub fn strs(&self) -> Option<&'static str>

Returns Some("PI_...","brief summary"), or None if the error code was not recognised.

impl Eq for PigpiodError

impl Hash for PigpiodError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

impl Ord for PigpiodError

fn cmp(&self, other: &PigpiodError) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<PigpiodError> for PigpiodError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<PigpiodError> for PigpiodError

fn partial_cmp(&self, other: &PigpiodError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &PigpiodError) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &PigpiodError) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &PigpiodError) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &PigpiodError) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
