Trait WritableElement 

pub trait WritableElement: Sized {
    // Required methods
    fn type_descriptor() -> PyValue;
    fn write<W: Write>(&self, writer: W) -> Result<(), WriteDataError>;
    fn write_slice<W: Write>(
        slice: &[Self],
        writer: W,
    ) -> Result<(), WriteDataError>;
}

An array element type that can be written to an .npy or .npz file.

Required Methods

fn type_descriptor() -> PyValue

Returns a descriptor of the type that can be used in the header.

fn write<W: Write>(&self, writer: W) -> Result<(), WriteDataError>

Writes a single instance of Self to the writer.

fn write_slice<W: Write>( slice: &[Self], writer: W, ) -> Result<(), WriteDataError>

Writes a slice of Self to the writer.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
