Struct imxrt_hal::dma::Error

pub struct Error { /* private fields */ }

A wrapper around a DMA error status value

The wrapper contains a copy of the DMA controller’s error status register at the point of an error. The wrapper implements both Debug and Display. Format the error to see a summary of the error bits.

Implementations

impl Error

pub const fn raw(self) -> u32

Returns the raw error status value

pub const fn is_valid(self) -> bool

Logical OR of all DMA channel error status bits

If you have an Error this should always be true.

pub const fn is_cancelled(self) -> bool

Indicates if the transfer was cancelled

pub const fn is_group_priority(self) -> bool

Indicates a group priority error

pub const fn is_channel_priority(self) -> bool

Indicates a channel priority error

pub const fn channel_number(self) -> u32

Indicates the channel number

pub const fn is_source_address(self) -> bool

Indicates a source address error

pub const fn is_source_offset(self) -> bool

Indicates a source offset error

pub const fn is_destination_address(self) -> bool

Indicates a destination address error

pub const fn is_destination_offset(self) -> bool

Indicates a destination offset error

pub const fn is_loop_configuration(self) -> bool

Indicates a minor / major loop configuration error

pub const fn is_scatter_gather(self) -> bool

Indicates a scatter / gather configuration error

pub const fn is_source_bus(self) -> bool

Indicates a source bus error

pub const fn is_destination_bus(self) -> bool

Indicates a destination bus error
