Expand description

A boxed cell output that can be stored generically.

Implementations§

Source§

impl BoxedOutput

Source

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

Create a new boxed output from a CellOutput.

Source

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.

Source

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.

Source

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.

Source

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

Get the serialized bytes.

Source

pub fn type_hash(&self) -> u64

Get the type hash.

Source

pub fn type_name(&self) -> &str

Get the type name.

Source

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

Get the display text (Debug format) if available.

Source

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

Deserialize to a specific type.

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