Trait TensorGenome 

Source 
pub trait TensorGenome: GenomeKind {
    type Tensor<B: Backend>: Clone + Debug + Send + Sync;
}
Expand description

Genome kinds with a rectangular, device-resident tensor representation.

This is the subset of GenomeKinds that a Population can store on-device. The associated Tensor type names which tensor flavour backs the kind, tying the storage type to the marker at compile time: Real maps to Tensor<B, 2>; Binary, Integer, and Permutation map to Tensor<B, 2, Int>.

Because the storage type is chosen by the trait impl, Population<B, K> needs only one field and no run-time tag — the wrong-tensor-for-this-kind state is simply unrepresentable. Variable-length kinds such as Tree have no rectangular form and deliberately do not implement this trait, so Population<B, Tree> is not a valid type.

Required Associated Types§

Source

type Tensor<B: Backend>: Clone + Debug + Send + Sync

Device tensor type storing a whole population of this kind, shape (pop_size, genome_dim).

The Send + Sync bound keeps Population<B, K> thread-safe under the crate-wide Strategy: Send + Sync contract: without it, generic code over K: TensorGenome could not prove the stored tensor — and therefore the population — is shareable across threads, even though every concrete Burn tensor is.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
