Struct Chain 

pub struct Chain {
    pub at: Addr,
    pub len: u64,
}

Where a value went, and how much of it there is.

Twelve bytes, which is what value::write_cold_record puts in a demoted record. at is the single chunk when the value fits in one and the directory when it does not, and len is what says which.

Fields

at: Addr

The one chunk, or the directory.

len: u64

The value’s length in bytes, not the chain’s.
