Implementations

impl Descriptor

const END_LINK: u32 = 4_294_965_248u32

pub const MAX_LEN: u32 = 33_554_431u32

Maximum length for arguments to DescriptorBuilder::source_slice and DescriptorBuilder::dest_slice, and to the len argument to DescriptorBuilder::try_build — byte counters must be 25 bits wide or less.

pub const ADDR_MAX: u64 = 17_179_869_183u64

Highest allowable address for arguments to DescriptorBuilder::source_slice, DescriptorBuilder::dest_slice, DescriptorBuilder::source_reg, and DescriptorBuilder::dest_reg — addresses must be 34 bits wide or less.

pub const LINK_ADDR_MAX: usize = 4_294_967_295usize

Maximum value for the link address passed to DescriptorBuilder::link – link addresses must be 32 bits wide or less.

pub const fn builder() -> DescriptorBuilder

pub fn set_link( &mut self, link: impl Into<Option<NonNull<Self>>>, ) -> Result<(), InvalidLink>

fn addr_to_link(link: NonNull<Self>) -> Result<u32, InvalidLink>
