Trait Field 

pub trait Field: Sized {
    const SIZE: Option<usize>;

    // Required methods
    fn read(buf: &[u8], offset: usize) -> Result<Self, FieldError>;
    fn write(&self, buf: &mut [u8], offset: usize) -> Result<(), FieldError>;
}

Trait for reading/writing protocol fields from raw buffers.

Required Associated Constants

const SIZE: Option<usize>

The size of this field in bytes (None for variable-length fields).

Required Methods

fn read(buf: &[u8], offset: usize) -> Result<Self, FieldError>

Read the field value from the buffer at the given offset.

fn write(&self, buf: &mut [u8], offset: usize) -> Result<(), FieldError>

Write the field value to the buffer at the given offset.

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.
