Struct BrowserFrame 

pub struct BrowserFrame {
    pub id: u64,
    pub status: Option<u16>,
    pub headers: Option<BTreeMap<String, String>>,
    pub body: Option<String>,
    pub encoding: Option<String>,
    pub error: Option<String>,
    pub stream: Option<bool>,
    pub chunk: Option<String>,
    pub seq: Option<u64>,
    pub done: Option<bool>,
}

Browser → server frame: a superset of BrowserReply plus the streaming fields (stream/chunk/seq/done).

The WebSocket reader deserialises every inbound frame into this struct, then interprets it as a buffered reply or a StreamItem depending on which waiter is registered for its id. Modelled as a flat struct of Options so one serde deserialise accepts every shape.

Fields

id: u64

Correlation id echoed from the Command.

status: Option<u16>

HTTP status code (buffered success, or a stream’s head frame).

headers: Option<BTreeMap<String, String>>

Response headers (buffered success, or a stream’s head frame).

body: Option<String>

Buffered response body.

encoding: Option<String>

Buffered body transfer encoding (Some("base64") for binary bodies).

error: Option<String>

Error message when the browser fetch() failed.

stream: Option<bool>

Some(true) on the first frame of a streamed response (head: status + headers, no body yet).

chunk: Option<String>

Base64-encoded body chunk of a streamed response.

seq: Option<u64>

Monotonic chunk sequence number within a stream.

done: Option<bool>

Some(true) on the terminating frame of a streamed response.

Implementations

impl BrowserFrame

pub fn into_reply(self) -> BrowserReply

Interprets this frame as a buffered reply (the back-compat path taken when the registered waiter is a one-shot buffered request).

pub fn stream_item(self) -> StreamItem

Interprets this frame as a StreamItem (taken when the registered waiter is a stream). An error wins; then done; then a chunk; otherwise the frame is the stream’s head.

Trait Implementations

impl Clone for BrowserFrame

fn clone(&self) -> BrowserFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BrowserFrame

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BrowserFrame

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for BrowserFrame

impl PartialEq for BrowserFrame

fn eq(&self, other: &BrowserFrame) -> 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 BrowserFrame

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
