Struct SubmitEntry 

#[repr(C, align(64))]
pub struct SubmitEntry {
    pub opcode: u16,
    pub flags: u16,
    pub _reserved: u32,
    pub args: [u64; 5],
    pub user_data: u64,
}

Submission entry — a single kernel operation request.

Written by userspace, read by kernel. Each entry is cache-line aligned to prevent false sharing.

Fields

opcode: u16

Operation code (KernelOp discriminant).

flags: u16

Per-operation flags (see submit_flags).

_reserved: u32

Reserved.

args: [u64; 5]

Operation-specific arguments. Meaning depends on opcode.

user_data: u64

Opaque user token, returned in the corresponding CompleteEntry.

Implementations

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for SubmitEntry

fn default() -> Self
