Struct WebSocketMessage 

pub struct WebSocketMessage {
    pub type: WebSocketMessageType,
    pub time: f64,
    pub opcode: WebSocketMessageOpcode,
    pub data: ArcStr,
}

Available on crate features http and std only.

A Chrome DevTools WebSocket message stored in an HAR entry’s _webSocketMessages extension.

Chrome exports complete text and binary messages rather than fragmented wire frames, plus protocol errors. Control frames and connection-close events are not included. The shape is unchanged from the Chrome 76 announcement and the current Chromium DevTools HAR exporter.

Fields

type: WebSocketMessageType

Whether the message was sent, received, or reports a protocol error.

time: f64

Unix timestamp in seconds, including any fractional part.

Unlike HAR’s startedDateTime, Chromium emits this as a JSON number.

opcode: WebSocketMessageOpcode

WebSocket opcode, or WebSocketMessageOpcode::ERROR for an error record.

data: ArcStr

Message payload.

Text messages and error records contain their original text. Chromium’s DevTools Protocol supplies non-text message data as base64, so binary messages use a base64 string here.

Implementations

impl WebSocketMessage

pub fn new( type: WebSocketMessageType, time: f64, opcode: WebSocketMessageOpcode, data: impl Into<ArcStr>, ) -> WebSocketMessage

Create a message with an explicitly supplied opcode and already encoded data.

pub fn text( type: WebSocketMessageType, time: f64, data: impl Into<ArcStr>, ) -> WebSocketMessage

Create a text message (opcode: 1).

pub fn binary( type: WebSocketMessageType, time: f64, data: impl AsRef<[u8]>, ) -> WebSocketMessage

Create a binary message (opcode: 2), base64-encoding the supplied bytes.

pub fn binary_with_opcode( type: WebSocketMessageType, time: f64, opcode: WebSocketMessageOpcode, data: impl AsRef<[u8]>, ) -> WebSocketMessage

Create a non-text message and base64-encode its payload.

pub fn error(time: f64, message: impl Into<ArcStr>) -> WebSocketMessage

Create the error record shape used by Chromium (type: "error", opcode: -1).

pub fn binary_data(&self) -> Option<Result<Vec<u8>, DecodeError>>

Decode a binary message’s base64 payload.

Returns None for other opcodes. A malformed base64 payload remains visible as a decode error instead of being silently discarded.
