Enum Value 

pub enum Value {
    Str {
        off: u32,
        len: u32,
    },
    Int(u64),
    Signed(i64),
    Empty,
}

A typed cell. Str points into the owning Table’s arena (no lifetimes, no heap).

Variants

Str

A string, stored as an (offset, length) into the table’s arena.

Fields

off: u32

len: u32

Int(u64)

An unsigned integer.

Signed(i64)

A SIGNED integer: a reading that can be below zero. Pulled into existence by wifi list, whose signal is in dBm - always negative - and is the raw fact (utilities/0_conventions.md rule 7): the magnitude would be a different number, and a string would sort by bytes, which orders -9 after -80. Its own variant rather than a change to Int, so every count, size and tick keeps the type it had. Compares numerically with Int (sort, where) and is reduced by the aggregators through cell_num_wide (i128); only the u64 cell_int accessor refuses a negative.

Empty

An absent / null cell.
