Trait FixedSize 

pub trait FixedSize:
    Sized
    + Clone
    + Send
    + Sync
    + 'static {
    // Required methods
    fn read_from(buffer: &mut &[u8]) -> Result<Self>;
    fn write_to(&self, buffer: &mut BytesMut);
}

Trait for types that can be read/written as fixed-size values (synchronous version for columns)

All numeric types are stored in little-endian format in ClickHouse wire protocol.

Required Methods

fn read_from(buffer: &mut &[u8]) -> Result<Self>

Read a single fixed-size value from the buffer in little-endian byte order.

fn write_to(&self, buffer: &mut BytesMut)

Write a single fixed-size value to the buffer in little-endian byte order.

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.
