Implementations

impl PrimitiveType

pub fn is_bool(&self) -> bool

pub fn is_char(&self) -> bool

pub fn is_number(&self) -> bool

pub fn is_unit(&self) -> bool

pub fn to_number_type(&self) -> Option<NumberType>

pub fn from_type_name(tname: &str) -> Result<Self, ParseError>

Constructs a primitive value type from a Rust-based type string similar to what you would find from std::any::type_name

Examples

use entity::{PrimitiveType as PVT, NumberType as NT};

assert_eq!(
    PVT::from_type_name("bool").unwrap(),
    PVT::Bool,
);

assert_eq!(
    PVT::from_type_name("char").unwrap(),
    PVT::Char,
);

assert_eq!(
    PVT::from_type_name("u8").unwrap(),
    PVT::Number(NT::U8),
);

assert_eq!(
    PVT::from_type_name("()").unwrap(),
    PVT::Unit,
);
