Struct NcclCapabilities 

pub struct NcclCapabilities {
    pub version: (i32, i32, i32),
    pub has_fp8: bool,
    pub has_nvls: bool,
    pub has_sharp: bool,
}

Static description of the loaded NCCL library’s capabilities.

Fields

version: (i32, i32, i32)

(major, minor, patch). (0, 0, 0) if NCCL isn’t loadable.

has_fp8: bool

True iff nccl-fp8 feature is enabled and NCCL >= 2.20.

has_nvls: bool

True iff nccl-nvls feature is enabled. Whether NVLS is actually usable depends on topology — this flag indicates only that the build path is compiled in.

has_sharp: bool

SHARP support is reported via NCCL_NET_PLUGIN; this probe reports false until we wire the plugin query.

Implementations

impl NcclCapabilities

pub fn zeroed() -> Self

All-zero capabilities — the value returned when NCCL isn’t initialised on this host.

Trait Implementations

impl Clone for NcclCapabilities

fn clone(&self) -> NcclCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NcclCapabilities

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

Formats the value using the given formatter.

impl Default for NcclCapabilities

fn default() -> NcclCapabilities

Returns the “default value” for a type.

impl PartialEq for NcclCapabilities

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