Struct AvailableRing

#[repr(C)]
pub struct AvailableRing<'a> {
    size: usize,
    pub flags: &'a mut u16,
    pub idx: &'a mut u16,
    pub ring: &'a mut [u16],
    pub used_event: &'a mut u16,
}

Available ring structure

This structure is wrapped around the RawAvailableRing structure. It provides a safe interface to access the available ring entries.

Fields

size: usize

flags: &'a mut u16

idx: &'a mut u16

ring: &'a mut [u16]

used_event: &'a mut u16

Implementations

impl<'a> AvailableRing<'a>

pub unsafe fn new(size: usize, ptr: *mut RawAvailableRing) -> Self

Create a new AvailableRing instance

This function creates a new AvailableRing instance from a raw pointer to a RawAvailableRing.

Safety

This function is unsafe because it dereferences raw pointers and assumes that the memory layout is correct. The caller must ensure that the pointer is valid and points to a properly initialized RawAvailableRing.

Arguments

• size - The size of the ring.
• ptr - A raw pointer to a RawAvailableRing.

Returns

AvailableRing - A new AvailableRing instance.
