Enum hotg_rune_core::Value

#[non_exhaustive]
pub enum Value {
    Byte(u8),
    Short(i16),
    Integer(i32),
    Float(f32),
    SignedByte(i8),
}

A dynamically typed value that may be passed back and forth across the runtime.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Byte(u8)

Short(i16)

Integer(i32)

Float(f32)

SignedByte(i8)

Implementations

impl Value

pub const fn buffer() -> [u8; 8]

Get a buffer big enough to be used with Value::to_le_bytes().

pub fn from_le_bytes(ty: Type, bytes: &[u8]) -> Option<Self>

pub fn to_le_bytes(self, buffer: &mut [u8]) -> usize

Write this Value’s underlying value to the start of the provided buffer, returning the number of bytes written.

The buffer should have at least core::mem::size_of::<Value>() bytes. You can use the Value::buffer() helper for creating an adequately sized buffer.

pub fn ty(&self) -> Type
