Constant DYNAMIC 

pub const DYNAMIC: u64 = u64::MAX; // 18_446_744_073_709_551_615u64

Sentinel value for a dynamic dimension whose concrete size is not known at descriptor-write time.

In the wire encoding this is 0xFFFF_FFFF_FFFF_FFFF (UINT64_MAX). A reader MUST NOT compute buffer sizes, strides, or element counts for a tensor containing a dynamic dimension without first resolving it to a concrete value.

Examples

use hurray_core::{Shape, DYNAMIC};

let shape = Shape::new(vec![1, DYNAMIC, 768]).expect("valid shape");
assert!(shape.has_dynamic());
assert!(shape.element_count().is_none());
