Struct Header

pub struct Header {
    pub stream_id: String,
    pub timestamp: i64,
    pub topic: String,
    pub mime_type: String,
    pub total_length: Option<u64>,
    pub encryption_type: i32,
    pub attributes: HashMap<String, String>,
    pub content_header: Option<ContentHeader>,
}

main DataStream.Header that contains a oneof for specific headers

Fields

stream_id: String

unique identifier for this data stream

timestamp: i64

using int64 for Unix timestamp

topic: String

mime_type: String

total_length: Option<u64>

only populated for finite streams, if it’s a stream of unknown size this stays empty

encryption_type: i32

defaults to NONE

attributes: HashMap<String, String>

user defined attributes map that can carry additional info

content_header: Option<ContentHeader>

oneof to choose between specific header types

Implementations

impl Header

pub fn total_length(&self) -> u64

Returns the value of total_length, or the default value if total_length is unset.

pub fn encryption_type(&self) -> Type

Returns the enum value of encryption_type, or the default if the field is set to an invalid enum value.

pub fn set_encryption_type(&mut self, value: Type)

Sets encryption_type to the provided enum value.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Default for Header

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Header

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for Header

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Header

fn eq(&self, other: &Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Header

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
