Struct BoxedOutput 

pub struct BoxedOutput { /* private fields */ }

A boxed cell output that can be stored generically.

Implementations

impl BoxedOutput

pub fn new<T: CellOutput>(value: &T) -> Result<Self>

Create a new boxed output from a CellOutput.

pub fn from_raw_bytes(bytes: Vec<u8>) -> Self

Create a boxed output from raw serialized bytes.

Used when loading outputs from FFI calls where type info is not available at the Rust level.

Note: Type hash is set to 0 (unknown type). This is safe because deserialization validates types at runtime. Full type propagation from FFI would require codegen changes to embed type metadata in dylibs.

pub fn from_raw_bytes_with_display(bytes: Vec<u8>, display: String) -> Self

Create a boxed output from raw bytes with display text.

Used when loading outputs from FFI calls that include a human-readable representation.

pub fn from_raw_with_type( bytes: Vec<u8>, type_hash: u64, type_name: String, ) -> Self

Create a boxed output from raw bytes with known type info.

Used when restoring outputs from Salsa cache where type information was preserved.

pub fn bytes(&self) -> &[u8]

Get the serialized bytes.

pub fn type_hash(&self) -> u64

Get the type hash.

pub fn type_name(&self) -> &str

Get the type name.

pub fn display_text(&self) -> Option<&str>

Get the display text (Debug format) if available.

pub fn deserialize<T>(&self) -> Result<T>

where T: CellOutput + Archive, T::Archived: Deserialize<T, Strategy<Pool, Error>>,

Deserialize to a specific type.

Returns an error if the type hash doesn’t match.

Trait Implementations

impl Archive for BoxedOutput

where Vec<u8>: Archive, u64: Archive, String: Archive, Option<String>: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedBoxedOutput

The archived representation of this type.

type Resolver = BoxedOutputResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for BoxedOutput

fn clone(&self) -> BoxedOutput

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BoxedOutput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<BoxedOutput, __D> for Archived<BoxedOutput>

where Vec<u8>: Archive, <Vec<u8> as Archive>::Archived: Deserialize<Vec<u8>, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, String: Archive, <String as Archive>::Archived: Deserialize<String, __D>, Option<String>: Archive, <Option<String> as Archive>::Archived: Deserialize<Option<String>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<BoxedOutput, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<__S: Fallible + ?Sized> Serialize<__S> for BoxedOutput

where Vec<u8>: Serialize<__S>, u64: Serialize<__S>, String: Serialize<__S>, Option<String>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
