Writing of objects to a Write implementation

Required Methods§

source

fn write_to(&self, out: &mut dyn Write) -> Result<()>

Write a representation of this instance to out.

source

fn kind(&self) -> Kind

Returns the type of this object.

source

fn size(&self) -> u64

Returns the size of this object’s representation (the amount of data which would be written by write_to).

size’s value has no bearing on the validity of the object, as such it’s possible for size to return a sensible value but write_to to fail because the object was not actually valid in some way.
