Trait npy::NpyRecord

pub trait NpyRecord: Sized {
    fn get_dtype() -> Vec<(&'static str, DType)>;
    fn n_bytes() -> usize;
    fn read(_: &[u8]) -> Self;
    fn write<W: Write>(&self, writer: &mut W) -> Result<()>;
}

A trait representing a (de-)serializable data-structure.

If one wants to serialize a Vec<Foo>, the Foo must implement NpyRecord.

This trait is often automatically implemented by a #[derive(NpyRecord)]. This can be done for a struct where all fields implement Serializable.

Required Methods

fn get_dtype() -> Vec<(&'static str, DType)>

Get a vector of pairs (field_name, DType) representing the struct type.

fn n_bytes() -> usize

Get the number of bytes of this record in the serialized representation

fn read(_: &[u8]) -> Self

Deserialize binary data to a single instance of Self

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

Write Self in a binary form to a writer.
