pub fn memory_usage_parser(arg: &str) -> Result<MemoryUsage>Expand description
Parses a batch size.
This function accepts either a number (possibly followed by a
SI or NIST multiplier k, M, G, T, P, ki, Mi, Gi, Ti, or Pi), or a percentage
(followed by a %) that is interpreted as a percentage of the core
memory. If the value ends with a b or B it is interpreted as a number of
bytes, otherwise as a number of elements.
