Struct InodeKey 

#[repr(C)]
pub struct InodeKey {
    pub ino: u64,
    pub dev: u32,
    pub gen: u32,
}

Key used to identify an inode in BPF maps.

ABI and kernel assumptions

This struct is #[repr(C)] and used across the eBPF/userspace boundary, so its layout must remain in sync with the corresponding kernel/BPF-side definition.

The dev field stores the kernel’s encoded dev_t value (e.g. from super_block.s_dev) as a u32. On modern Linux kernels, this uses the new_encode_dev() format: (minor & 0xff) | ((major & 0xfff) << 8) | ((minor & 0xfffff00) << 12) This matches sb->s_dev seen by eBPF.

Fields

ino: u64

dev: u32

gen: u32

Trait Implementations

impl Clone for InodeKey

fn clone(&self) -> InodeKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InodeKey

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

Formats the value using the given formatter.

impl Hash for InodeKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InodeKey

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