Trait ArrayElement 

pub trait ArrayElement: Sealed + Copy {
    const SCALAR: ScalarType;

    // Required methods
    fn to_bytes(self) -> Vec<u8> ;
    fn from_element(element: &Element) -> Option<Self>;
}

A scalar type an array can be written from and read back as.

Implemented for the numeric types ASDF’s core/ndarray schema names, so AsdfBuilder::set_array and AsdfFile::read_array_of work for any of them without a method per type.

Sealed: the set of scalar types is the schema’s, not the caller’s.

Required Associated Constants

const SCALAR: ScalarType

The schema’s name for this type.

Required Methods

fn to_bytes(self) -> Vec<u8>

This value’s bytes in the machine’s own order.

fn from_element(element: &Element) -> Option<Self>

Read a decoded element as this type, or None if it is not one.

Narrowing that would lose the value is a None rather than a silent truncation: a caller asking for Vec<i32> wants the numbers, not whatever survives the cast.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
