Struct Union

Source
pub struct Union<'a> {
    pub _tab: Table<'a>,
}
Expand description

A union is a complex type with children in Field By default ids in the type vector refer to the offsets in the children optionally typeIds provides an indirection between the child offset and the type id for each child typeIds[offset] is the id used in the type vector

impl<'a> PartialEq for Union<'a>

Source§

fn eq(&self, other: &Union<'a>) -> bool

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
