Struct BridgeTensor 

pub struct BridgeTensor { /* private fields */ }

A type-tagged tensor at the bridge layer between the high-level tensor API and the dispatch system.

BridgeTensor serves as the runtime representation for the public tensor kinds (Float, Int, Bool) and internal variants like quantized floats, wrapping the uniform DispatchTensor used by the underlying dispatch layer. This separation keeps tensor kind tracking out of the backends while avoiding exposure of backend-level primitives in the public API.

Implementations

pub fn kind(&self) -> BridgeKind

Returns the runtime tag identifying which variant this tensor wraps.

pub fn is_float(&self) -> bool

Returns true if this tensor is the float variant.

pub fn is_int(&self) -> bool

Returns true if this tensor is the int variant.

pub fn is_bool(&self) -> bool
