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<'de, F, T> Deserialize<'de, As<F>> for Twhere F: BareFormula + ?Sized, T: Deserialize<'de, F>,

fn deserialize( deserializer: Deserializer<'de> ) -> Result<Self, DeserializeError>where Self: Sized,

Deserializes value provided deserializer. Returns deserialized value and the number of bytes consumed from the and of input.

fn deserialize_in_place( &mut self, deserializer: Deserializer<'de> ) -> Result<(), DeserializeError>

Deserializes value in-place provided deserializer. Overwrites self with data from the input.

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.

impl<F, T> Serialize<As<F>> for Twhere F: BareFormula + ?Sized, T: Serialize<F>,

fn serialize<B>(self, sizes: &mut Sizes, buffer: B) -> Result<(), B::Error>where Self: Sized, B: Buffer,

Serializes self into the given buffer. heap specifies the size of the buffer’s heap occupied prior to this call.

fn size_hint(&self) -> Option<Sizes>

Returns heap and stack sizes required to serialize self. If some sizes are returned they must be exact.
