ObjectData

Enum ObjectData 

Source
pub enum ObjectData<'a> {
    Empty,
    Inline(OutputData<'a>),
    Groups(Vec<Vec<OutputData<'a>>>),
}
Expand description

The data attached to an Archived::Object.

typedstream objects store their values in one or more groups (each group is the result of decoding one type descriptor). In practice the overwhelming majority of objects hold a single group containing a single value (an NSString’s text, an NSNumber’s number, a reference to another object) so that case is stored inline without any heap allocation. Only objects with multiple groups, or a group holding multiple values, fall back to the nested Vec representation.

Variants§

§

Empty

The object has no data groups.

§

Inline(OutputData<'a>)

A single group containing a single value, stored inline. This is by far the most common shape and avoids two heap allocations per object.

§

Groups(Vec<Vec<OutputData<'a>>>)

The general case: one or more groups, each holding one or more values.

Implementations§

Source§

impl<'a> ObjectData<'a>

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

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