Expand description
Trait implemented by any type that can be used as a dimension. This includes type-level
integers and Dynamic (for dimensions not known at compile-time).
Required methods
fn try_to_usize() -> Option<usize>
fn try_to_usize() -> Option<usize>
Gets the compile-time value of Self. Returns None if it is not known, i.e., if Self = Dynamic.
Gets the run-time value of self. For type-level integers, this is the same as
Self::try_to_usize().unwrap().
fn from_usize(dim: usize) -> Self
fn from_usize(dim: usize) -> Self
Builds an instance of Self from a run-time value. Panics if Self is a type-level
integer and dim != Self::try_to_usize().unwrap().
