Function Documentation

buffer_location_to_file_location()

uint64_t sysio::chain::detail::buffer_location_to_file_location ( uint32_t buffer_location )

constexpr

Definition at line 174 of file block_log.cpp.

{ return buffer_location << 3; }

calcluate_max_depth()

int sysio::chain::detail::calcluate_max_depth ( uint64_t node_count )

constexpr

Given a number of nodes return the depth required to store them in a fully balanced binary tree.

Parameters

node_count

- the number of nodes in the implied tree

Returns

the max depth of the minimal tree that stores them

Definition at line 59 of file incremental_merkle.hpp.

                                                       {

clz_power_2()

int sysio::chain::detail::clz_power_2 ( uint64_t value )

constexpr

Given a power-of-2 (assumed correct) return the number of leading zeros

This is a classic count-leading-zeros in parallel without the necessary math to make it safe for anything that is not already a power-of-2

Parameters

value

- and integral power-of-2

Returns

the number of leading zeros
