Trait xc3_write::Xc3Write

pub trait Xc3Write {
    type Offsets<'a>
       where Self: 'a;

    const ALIGNMENT: u64 = 4u64;

    // Required method
    fn xc3_write<W: Write + Seek>(
        &self,
        writer: &mut W
    ) -> Xc3Result<Self::Offsets<'_>>;

    // Provided method
    fn should_write(&self) -> Option<bool> { ... }
}

The write pass that writes fields and placeholder offsets.

Required Associated Types

type Offsets<'a> where Self: 'a

The type storing offset data to be used in Xc3WriteOffsets.

Provided Associated Constants

const ALIGNMENT: u64 = 4u64

The alignment of absolute offsets for this type in bytes.

Required Methods

fn xc3_write<W: Write + Seek>( &self, writer: &mut W ) -> Xc3Result<Self::Offsets<'_>>

Write all fields and placeholder offsets. This should almost always be derived for non primitive types.

Provided Methods

fn should_write(&self) -> Option<bool>

Return Some(_) if the offset should be updated and Some(true) if the data should also be written. Defaults to Some(true).

Object Safety

This trait is not object safe.
