Struct AttributeMessage 

pub struct AttributeMessage {
    pub name: String,
    pub dtype: DataType,
    pub dataspace: DataspaceMessage,
    pub raw_value: Bytes,
}

An HDF5 attribute (name-value pair attached to a group or dataset).

Message type 0x000C.

Fields

name: String

Attribute name.

dtype: DataType

Data type of the attribute value.

dataspace: DataspaceMessage

Dataspace (dimensionality) of the attribute.

raw_value: Bytes

Raw value bytes.

Implementations

impl AttributeMessage

pub fn decode(&self) -> AttributeValue

Decode the raw value bytes into a typed AttributeValue.

pub fn to_attribute(&self) -> Attribute

Convert this message to a resolved Attribute with decoded value.

pub async fn decode_with_reader( &self, reader: &Arc<dyn AsyncFileReader>, size_of_offsets: u8, size_of_lengths: u8, ) -> Result<AttributeValue>

Decode the raw value, resolving variable-length data via the global heap.

This handles the common case of vlen strings written by h5py (the default). Falls back to decode() for non-vlen types.

pub async fn to_attribute_resolved( &self, reader: &Arc<dyn AsyncFileReader>, size_of_offsets: u8, size_of_lengths: u8, ) -> Result<Attribute>

Async version of to_attribute that resolves vlen data.

pub fn parse( data: &Bytes, size_of_offsets: u8, size_of_lengths: u8, ) -> Result<Self>

Parse from the raw message bytes.

Trait Implementations

impl Clone for AttributeMessage

fn clone(&self) -> AttributeMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeMessage

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

Formats the value using the given formatter.
