Type casting logics between Rust and mruby

Rust type	mruby type
i8, i16, i32, i64, isize	Integer
u8, u16, u32, u64, usize	Integer
f32, f64	Float
String	String
Option<T>	T or nil
(T, U), (T, U, V), etc	[T, U], [T, U, V], etc
Vec<T>	Array
std::collections::HashMap<T, U>	Hash
minutus::types::RSymbol	Symbol
bool	any object
MrbData (structs marked by minutus::wrap)	corresponding class

Any value in mruby can be cast to Rust’s bool. Rust’s bool cast to mruby’s true or false.

Structs

• MrbConversionError
• MrbValue
  Represents values returned from mruby world.
• RSymbol
  Represents mruby’s symbol.

Traits

• IntoArgs
• MrbValueLike
• ToSymbol
  Extension trait that defines to_sym method.
• TryFromMrb
  Trait that handles casting mruby value into Rust value.
• TryIntoMrb
  Trait that handles casting Rust value into mruby value.
