Struct DmaConstraints 

pub struct DmaConstraints {
    pub addr_mask: u64,
    pub align: usize,
    pub boundary: Option<usize>,
    pub max_segment_size: Option<usize>,
}

Device-visible DMA constraints.

Fields

addr_mask: u64

align: usize

boundary: Option<usize>

max_segment_size: Option<usize>

Implementations

impl DmaConstraints

pub const fn new(addr_mask: u64) -> Self

pub fn with_align(self, align: usize) -> Self

pub fn with_boundary(self, boundary: usize) -> Self

pub fn with_max_segment_size(self, max_segment_size: usize) -> Self

Trait Implementations

impl Clone for DmaConstraints

fn clone(&self) -> DmaConstraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DmaConstraints

impl Debug for DmaConstraints

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

Formats the value using the given formatter.

impl Eq for DmaConstraints

impl PartialEq for DmaConstraints

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