#[non_exhaustive]
pub enum Value {
    Byte(u8),

Expand description

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

Variants (Non-exhaustive)

This enum is marked as 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.
