Detailed Description

Variable Length Unsigned Integer. This provides more efficient serialization of 32-bit unsigned int. It serialuzes a 32-bit unsigned integer in as few bytes as possible varuint32 is unsigned and uses VLQ or Base-128 encoding

Returns:

T - Converted target

function operator=

unsigned_int& unsigned_int::operator=(
    uint32_t v
)

Assign 32-bit unsigned integer

Parameters:

  • v - Soruce

Returns:

unsigned_int& - Reference to this object
