Enum MetadataValue 

#[non_exhaustive]
pub enum MetadataValue {
    String(String),
    StringList(Vec<String>),
    F64(f64),
    I64(i64),
    Bool(bool),
    Tensor(Tensor),
}

Free-form metadata values attached to graphs and nodes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

String(String)

UTF-8 string.

StringList(Vec<String>)

List of UTF-8 strings.

Python’s metadata: Dict[str, Any] admits a list[str], which h5py stores as a multi-element string dataset. Without this variant such a file cannot be decoded at all, since Tensor carries only numeric and boolean payloads.

F64(f64)

64-bit float.

I64(i64)

64-bit signed integer.

Bool(bool)

Boolean.

Tensor(Tensor)

Dense tensor.
