Expand description

Trait for any DICOM entity (element or item) which may have a length.

Required Methods§

source

fn length(&self) -> Length

Retrieve the value data’s length as specified by the data element or item, in bytes.

It is named length to make it distinct from the conventional method signature len(&self) -> usize for the number of elements of a collection.

According to the standard, the concrete value size may be undefined, which can be the case for sequence elements or specific primitive values.

Provided Methods§

source

fn is_empty(&self) -> bool

Check whether the value is empty (0 length).
