Enum EncodingDatum 

pub enum EncodingDatum<TEncoding: TermEncoding + ?Sized> {
    Array(TEncoding::Array),
    Scalar(TEncoding::Scalar, usize),
}

Represents either an array or a scalar for a given encoding.

As the scalar variant also stores length information, one can obtain an iterator (Self::term_iter) independently on whether the underlying data is an array or a scalar. This is useful for scenarios in which distinguishing between array/scalar is not necessary or too complex.

Variants

Array(TEncoding::Array)

An array underlies this datum.

Scalar(TEncoding::Scalar, usize)

A scalar underlies this datum. The additional length value is crucial for creating an iterator of a given length.

Implementations

impl<TEncoding: TermEncoding + ?Sized> EncodingDatum<TEncoding>

pub fn term_iter<'data, TDecoder>( &'data self, ) -> Box<dyn Iterator<Item = ThinResult<TDecoder::Term<'data>>> + 'data>

where TDecoder: TermDecoder<TEncoding> + 'data,

Creates an iterator over the contents of this datum.

For an array, the iterator will simply return the result from the decoder.

For a scalar, the value of the scalar will be cloned for each iteration, as dictated by the additional length.

pub fn to_array(&self) -> TEncoding::Array

Creates an array for this datum.
