Struct CommandId 

pub struct CommandId(/* private fields */);

Opaque command identifier. Wrap an enum variant (or a u32) to make it comparable and hashable without storing strings at runtime.

Example

use egui_command::CommandId;

#[derive(Debug, Clone, Copy, PartialEq, Eq, Hash)]
enum AppCmd {
    ShowHelp,
    RenameProfile,
}

let id = CommandId::new(AppCmd::ShowHelp);
assert_eq!(id, CommandId::new(AppCmd::ShowHelp));
assert_ne!(id, CommandId::new(AppCmd::RenameProfile));

Implementations

impl CommandId

pub fn new<T: Hash>(value: T) -> Self

Create a CommandId from any value that can be hashed.

Uses FxHasher — a deterministic, platform-stable hasher — so that the same value always produces the same CommandId across process restarts, Rust versions, and platforms.

pub fn raw(self) -> u64

Raw numeric value.

The underlying hash is stable within a build (same input → same output across runs, versions, and platforms when using the same FxHasher). Suitable for in-memory keying; treat persistence across binary upgrades with caution unless the hashed type’s discriminant is stable.

pub fn from_raw(v: u64) -> Self

Construct from a raw value (e.g. round-tripping through an integer key).

Trait Implementations

impl Clone for CommandId

fn clone(&self) -> CommandId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandId

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

Formats the value using the given formatter.

impl Hash for CommandId

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 CommandId

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