Struct PackedU64 

pub struct PackedU64(/* private fields */);

A 64-bit number kept at the alignment of a 32-bit word on ESP-IDF. There a u64 takes 8-byte alignment, and so would every record that holds one: padding around the field, and on a heap that hands out 4-byte aligned blocks, a block 8 bytes longer. Elsewhere it is a u64, which the compiler reads and compares without copying it out of a packed field.

Implementations

impl PackedU64

pub const fn new(value: u64) -> Self
