Enum Data 

pub enum Data<'s> {
    Null,
    Boolean(bool),
    Integer(i64),
    String(AtprotoStr<'s>),
    Bytes(Bytes),
    CidLink(Cid<'s>),
    Array(Array<'s>),
    Object(Object<'s>),
    Blob(Blob<'s>),
}

AT Protocol data model value

Represents any valid value in the AT Protocol data model, which supports JSON and CBOR serialization with specific constraints (no floats, CID links, blobs with metadata).

This is the generic “unknown data” type used for lexicon values, extra fields captured by #[lexicon], and IPLD data structures.

Variants

Null

Null value

Boolean(bool)

Boolean value

Integer(i64)

Integer value (no floats in AT Protocol)

String(AtprotoStr<'s>)

String value (parsed into specific AT Protocol types when possible)

Bytes(Bytes)

Raw bytes

CidLink(Cid<'s>)

CID link reference

Array(Array<'s>)

Array of values

Object(Object<'s>)

Object/map of values

Blob(Blob<'s>)

Blob reference with metadata

Implementations

impl<'s> Data<'s>

pub fn data_type(&self) -> DataModelType

Get the data model type of this value

pub fn from_json(json: &'s Value) -> Result<Self, AtDataError>

pub fn from_cbor(cbor: &'s Ipld) -> Result<Self, AtDataError>

Trait Implementations
