Struct CommandRegistration 

pub struct CommandRegistration {
    pub id: &'static str,
    pub name: &'static str,
    pub description: &'static str,
    pub category: Option<&'static str>,
    pub depends_on: &'static [&'static str],
    pub flags: RegistrationFlags,
    /* private fields */
}

Command registration descriptor.

Linux equivalent: Like struct file_operations - declares command capabilities.

Fields align with CommandTrait from the original design (see archive/pre_kernel/lib/core/src/command/traits.rs).

Command capabilities (accepts count, accepts motion, is jump, is text-modifying) are stored as a u8 bitfield to preserve kernel purity (zero external deps).

Fields

id: &'static str

Unique command identifier (e.g., “delete”, “yank”, “motion:word”).

name: &'static str

Human-readable name for help display.

description: &'static str

Description for help system.

category: Option<&'static str>

Category for help grouping (e.g., “motion”, “operator”, “edit”).

depends_on: &'static [&'static str]

Dependencies on other commands (Linux: module dependencies).

flags: RegistrationFlags

Registration flags.

Implementations
