}

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) -> TractResult<(Self, u64)>

fn to_i64(&self) -> TractResult<i64>

Convert to regular integer.

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

Substitute as many symbols as possible in the dim value.

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

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

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

fn broadcast(self, other: Self) -> TractResult<Self>

fn mini(self, other: Self) -> Self

fn maxi(self, other: Self) -> Self

fn compatible_with(&self, other: &Self) -> bool

Provided Methods

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

Integer divise, rounding up to next integer.

fn to_usize(&self) -> TractResult<usize>

fn to_isize(&self) -> TractResult<isize>

fn to_i32(&self) -> TractResult<i32>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
