Struct alkahest::As

pub struct As<F: ?Sized> { /* private fields */ }

Formula type that mirrors specified formula F. It can be used to turn unsized field type into sized one, keeping the same formula.

Example

type MyFormula = [str]; // Slice element type must be sized. `str` is unsized.

let mut buffer = [0u8; 22];
serialize::<MyFormula, _>(["qwe", "rty"], &mut buffer).unwrap();

// Wrap usized type into As

type MyFormula = [As<str>]; // `As` is always size.



let mut buffer = [0u8; 22];

serialize::<MyFormula, _>(["qwe", "rty"], &mut buffer).unwrap();

Trait Implementations

impl<F> Formula for As<F>where F: BareFormula + ?Sized,

const MAX_STACK_SIZE: Option<usize> = F::MAX_STACK_SIZE

Maximum size of stack this formula occupies.

const EXACT_SIZE: bool = F::EXACT_SIZE

Signals that MAX_STACK_SIZE is accurate.

const HEAPLESS: bool = F::HEAPLESS

Signals that heap is not used for serialzation.
