Struct DescTable 

pub struct DescTable { /* private fields */ }

A table of descriptors stored in shared memory.

Implementations

impl DescTable

pub const DEFAULT_LEN: usize = 256

pub unsafe fn from_raw_parts(base_addr: u64, len: usize) -> Self

Create a descriptor table from shared memory.

Safety

• base_addr must be valid for reads and writes of len descriptors
• base_addr must be properly aligned for Descriptor
• len must not exceed u16::MAX
• memory must remain valid for the lifetime of this table

pub fn desc_addr(&self, idx: u16) -> Option<u64>

Get view into descriptor at index or None if idx is out of bounds

pub fn len(&self) -> usize

Get number of descriptors in table

pub fn is_empty(&self) -> bool

Is the descriptor table empty?

pub const fn default_len() -> usize
