Struct Role 

pub struct Role { /* private fields */ }

A role within a warp (e.g., coordinator vs worker lanes).

Roles enable modeling warp-level protocols where different lanes have different responsibilities. Uses u64 mask to match ActiveSet::MASK width (supporting AMD 64-lane wavefronts).

Implementations

impl Role

pub const fn mask(self) -> u64

The bitmask of lanes in this role.

pub const fn name(self) -> &'static str

Human-readable role name.

impl Role

pub const fn lanes(start: u8, end: u8, name: &'static str) -> Self

pub const fn lane(id: u8, name: &'static str) -> Self

pub const fn contains(self, lane: LaneId) -> bool

pub const fn count(self) -> u32

Trait Implementations

impl Clone for Role

fn clone(&self) -> Role

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Role

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

Formats the value using the given formatter.

impl PartialEq for Role

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

impl Copy for Role

impl Eq for Role

impl StructuralPartialEq for Role
