Struct TransferOptions 

#[non_exhaustive]
pub struct TransferOptions {
    pub priority: Priority,
    pub half_transfer_ir: bool,
    pub complete_transfer_ir: bool,
    pub secure: bool,
    pub burst_length: Burst,
}

GPDMA transfer options.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

priority: Priority

Request priority level.

half_transfer_ir: bool

Enable half transfer interrupt.

complete_transfer_ir: bool

Enable transfer complete interrupt.

secure: bool

Issue source and destination AXI/AHB transactions with the secure attribute set (TR1.SSEC = TR1.DSEC = 1). Required when the channel is configured secure (SECCFGR.SEC[n]=1) and the slave is behind RISAF — without this the channel hits ULEF (user setting error) after partial progress. Default false.

burst_length: Burst

Burst length on both source and destination ports. Default Single. Some peripherals (notably the JPEG codec on N6) only assert their DMA request line for bursts above a threshold.

Trait Implementations

impl Clone for TransferOptions

fn clone(&self) -> TransferOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransferOptions

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

Formats the value using the given formatter.

impl Default for TransferOptions

fn default() -> Self

Returns the “default value” for a type.

impl Format for TransferOptions

where Priority: Format, Burst: Format,

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

Writes the defmt representation of self to fmt.

impl PartialEq for TransferOptions

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