Member Function Documentation

ReadOne()

std::optional< uint64_t > wpi::Uleb128Reader::ReadOne

(

std::span< const uint8_t > *

in

)

Decode a single ULEB128 value.

Returns after a single ULEB128 value has been read or insufficient input (call in a loop to get multiple values). If a value is returned, internal state is reset so it's safe to immediately call this function again to decode another value.

Parameters

in	Input data; modified as data is consumed (any unconsumed data is left when function returns).

Returns

value (in std::optional)
