Enum Dimension 

pub enum Dimension {
    Fixed(u32),
    Dynamic(Option<String>),
    Symbolic(String),
}

A single tensor dimension: either a fixed size, a named symbolic parameter, or fully dynamic (unknown at compile time).

Variants

Fixed(u32)

Fixed (static) size known at compile time.

Dynamic(Option<String>)

Dynamic (unknown) dimension with an optional name (e.g. “batch”).

Symbolic(String)

Symbolic dimension with a named constraint (e.g. “batch”, “seq_len”).

Unlike Dynamic, symbolic dimensions carry a semantic constraint: all dimensions sharing the same symbolic name must have the same runtime value. This enables shape validation across tensor operands.

Implementations

impl Dimension

pub fn is_fixed(&self) -> bool

Returns true if this dimension is statically known.

pub fn is_dynamic(&self) -> bool

Returns true if this dimension is dynamic (either unnamed or named).

pub fn is_symbolic(&self) -> bool

Returns true if this dimension is symbolic (named constraint).

pub fn fixed_size(&self) -> Option<u32>

Returns the fixed size, if known.

pub fn symbolic_name(&self) -> Option<&str>

Returns the symbolic name, if any.
