Rust - Scalar Types

 

Integers:

Unsigned   Signed

u8 - i8

u16 - i16

u32 - i32

u64 - i64

u128 - i128

usize - isize -- equal to platform size


float: 

f32

f64



let x = 5_u16;   and  let x = 5u16; and let x:u16 = 5; are same.

let y = 3.14_f32   and  let y = 3.14f32 and let y:f32 = 3.14; are same;


boolean


true,false


char is not 8byte. Any action sound to emoj and character. Useless..

BIOFLOC

  Biofloc  Fish Farming Biofloc  technology What is  biofloc ? Biofloc  is the macro-aggregation of bacteria, algae, detritus and other decomposed components associated with extracellular polymeric substances. It is the combination of bacteria, diatoms, zooplankton, protozoa, macro-algae, faeces, uneaten feed, and exoskeleton from dead organisms. What is  biofloc  technology (BFT)? BFT is an innovative and cost-effective technology.  It is based on the principle of waste nutrients recycling, in particular nitrogen, into microbial biomass that can be used as feed by the cultured animals. Heterotrophic bacteria are stimulated to grow by controlling the C:N ratio in the water through the modification of the carbohydrate content in the feed or by the addition of an external carbon source in the water, so that the bacteria can assimilate the waste ammonium for new biomass production. Hence, ammonia can be maintained at a low and non‐toxic concentration...
