Implementations

impl DynTensor

pub fn from_string_array<T: Utf8Data>( allocator: &Allocator, input: impl IntoValueTensor<Item = T> ) -> Result<DynTensor>

Construct a Value from an array of strings.

Just like numeric tensors, string tensor Values can be created from:

• (with feature ndarray) a shared reference to a ndarray::CowArray (&CowArray<'_, T, D>);
• (with feature ndarray) a mutable/exclusive reference to an ndarray::ArcArray (&mut ArcArray<T, D>);
• (with feature ndarray) an owned ndarray::Array;
• (with feature ndarray) a borrowed view of another array, as an ndarray::ArrayView (ArrayView<'_, T, D>);
• a tuple of (dimensions, data) where:
  • dimensions is one of Vec<I>, [I] or &[I], where I is i64 or usize;
  • and data is one of Vec<T>, Box<[T]>, Arc<Box<[T]>>, or &[T].

// You'll need to obtain an `Allocator` from a session in order to create string tensors.
let allocator = session.allocator();

// Create a string tensor from a raw data vector
let data = vec!["hello", "world"];
let value = Value::from_string_array(allocator, ([data.len()], data.into_boxed_slice()))?;

// Create a string tensor from an `ndarray::Array`
#[cfg(feature = "ndarray")]
let value = Value::from_string_array(
	allocator,
	ndarray::Array::from_shape_vec((1,), vec!["document".to_owned()]).unwrap()
)?;

Note that string data will always be copied, no matter what form the data is provided in.
