Leonardo Yvens 9db7896e48 implement from and into RuntimeValue for i8, u8, i16 and u16 (#104) 
This works under the assumption that these values
are represented as an `I32` in WASM, which seems
reasonable.
 2018-06-25 16:59:30 +03:00
Leonardo Yvens 75406dd8ff Use transmute instead of casts In RuntimeValue conversion. (#102) 
Casts have arithmetic semantics, and under some build configurations
Rust will panic when encountering an arithmetic overflow.
Use a transmute instead since it's what we mean.
The previous code worked, but still I added a test for good measure.
