Struct AttributeMessage 

pub struct AttributeMessage {
    pub name: String,
    pub datatype: Datatype,
    pub dataspace: Dataspace,
    pub raw_data: Vec<u8>,
}

A parsed HDF5 attribute message.

Fields

name: String

Attribute name.

datatype: Datatype

Attribute datatype.

dataspace: Dataspace

Attribute dataspace.

raw_data: Vec<u8>

Raw attribute value data.

Implementations

impl AttributeMessage

pub fn parse( data: &[u8], length_size: u8, ) -> Result<AttributeMessage, FormatError>

Parse an attribute message from raw message bytes.

length_size is needed for dataspace dimension parsing.

pub fn serialize(&self, length_size: u8) -> Vec<u8>

Serialize attribute message (v2 format, no padding).

pub fn serialize_v3(&self, length_size: u8) -> Vec<u8>

Serialize attribute message as v3 (adds character set encoding byte).

pub fn read_as_f64(&self) -> Result<Vec<f64>, FormatError>

Read attribute value as f64 values.

pub fn read_as_i64(&self) -> Result<Vec<i64>, FormatError>

Read attribute value as i64 values.

pub fn read_as_u64(&self) -> Result<Vec<u64>, FormatError>

Read attribute value as u64 values.

pub fn read_as_string(&self) -> Result<String, FormatError>

Read attribute value as a single string (first element).

pub fn read_as_strings(&self) -> Result<Vec<String>, FormatError>

Read attribute value as a vector of fixed-length strings.

pub fn read_vl_strings( &self, file_data: &[u8], offset_size: u8, length_size: u8, ) -> Result<Vec<String>, FormatError>

Read variable-length string attribute values.

Needs the full file data and offset/length sizes from the superblock because VL strings store their data in the global heap.

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.
