A super-trait for value acting as tensor dimensions in tract.

Implemented by:

• usize for regular dimensions
• TDim supporting regular and streaming dimensions

Required Methods

fn maybe_div(&self, other: &Self) -> Result<(Self, u64), Error>

fn to_i64(&self) -> Result<i64, Error>

Convert to regular integer.

fn one() -> Self

do not use num_traits::Mul as it implies a regular Mul

fn eval(&self, values: &SymbolValues) -> Self

Substitute as many symbols as possible in the dim value.

fn eval_to_i64(&self, values: &SymbolValues) -> Result<i64, Error>

Full evaluation of the symbol, failing if a symbol is missing

fn substitute(&self, from: &Symbol, to: &Self) -> Self

Provided Methods

fn divceil(&self, other: usize) -> Self

Integer divise, rounding up to next integer.

fn to_usize(&self) -> Result<usize, Error>

fn to_isize(&self) -> Result<isize, Error>

fn to_i32(&self) -> Result<i32, Error>

Object Safety

This trait is not object safe.
