[dependabot]

Bumps tungstenite from 0.23.0 to 0.26.1.

Changelog

Sourced from tungstenite's changelog.

0.26.1

• Fix/revert unsoundness that could lead to UB with dodgy Read stream implementations.

0.26.0

• Simplify Message to use Bytes payload directly with simpler Utf8Bytes for text.
• Change CloseFrame to use Utf8Bytes for reason.
• Re-export Bytes.

0.25.0

• New Payload type for Message that allows sending messages with a payload that can be cheaply cloned (Bytes). Long standing issue solved!
• Add WebSocketConfig::read_buffer_size default 128 KiB.
• Make WebSocketConfig non-exhaustive & add builder style construction fns.
• Remove deprecated WebSocketConfig::max_send_queue.
• Trim spaces on Sec-WebSocket-Protocol header.
• Eliminate data copies when reading complete messages & optimise read buffer. Improves performance.
• Update thiserror to 2.

0.24.0

• Raised MSRV to 1.63 to match tokio-tungstenite.
• Connecting to WSS URL without TLS features specified results in a better error.
• Handshake will now flush after completion to be safe (works better with buffered streams).
