Enum Error

pub enum Error {
    LengthMismatch,
    InvalidState,
    TransferError,
}

Runtime errors that may occur when dealing with DMA transfers.

Variants

LengthMismatch

Supplied buffers both have lengths > 1 beat, but not equal to each other

Buffers need to either have the same length in beats, or one should have length == 1. In cases where one buffer is length 1, that buffer will be the source or destination of each beat in the transfer. If both buffers had length >1, but not equal to each other, then it would not be clear how to structure the transfer.

InvalidState

Operation is not valid in the current state of the object.

TransferError

Chip reported an error during transfer

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Format for Error

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(value: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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.
