Struct BlockBufferConfig 

pub struct BlockBufferConfig {
    pub block_size: NonZeroUsize,
    pub align: usize,
    pub dma_mask: Option<u64>,
}

Buffer and address constraints exposed by a host block queue.

Fields

block_size: NonZeroUsize

Logical block size accepted by the queue.

align: usize

Required CPU-buffer alignment in bytes.

dma_mask: Option<u64>

Device-visible DMA address mask, when the queue uses DMA.

Implementations

impl BlockBufferConfig

pub const fn new( block_size: NonZeroUsize, align: usize, dma_mask: Option<u64>, ) -> Self

Trait Implementations

impl Clone for BlockBufferConfig

fn clone(&self) -> BlockBufferConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockBufferConfig

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

Formats the value using the given formatter.

impl PartialEq for BlockBufferConfig

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