}

The MPR121 Device has an Enumeration of potential driver errors, which are held in the enum below

Variants

ChannelExceed

If an operation exceeds the channel count (typically 12).

ReadError(Register)

If a read operation failed, contains the address that failed.

DataConversionError(Register)

If a data conversion failed, contains the address that failed to convert from

WriteError(Register)

If a write operation failed, contains the address that failed.

ResetFailed

If sending the reset signal failed, contains the register that failed.

Fields

was_read: bool

reg: Register

OverCurrent

During Startup if there is an overcurrent detection, the driver will fail to initialise indicating a hardware fault

WrongDevice

Wrong Device Connected, this can also happen if the device state is invalid possible due to a short circuit/overcurrent event

Fields

mismatched_register: Register

expected: u8

actual: u8

Trait Implementations

impl Clone for Mpr121Error

fn clone(&self) -> Mpr121Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mpr121Error

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

Formats the value using the given formatter.

impl Ord for Mpr121Error

fn cmp(&self, other: &Mpr121Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Mpr121Error

fn eq(&self, other: &Mpr121Error) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Mpr121Error

fn partial_cmp(&self, other: &Mpr121Error) -> Option<Ordering>

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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