Expand description

The error returned from the read and read_sync methods.

Variants

`BufSize(TryFromIntError)`

Received a buffer with more than usize::MAX elements

`Custom(String)`

An error variant you can use when manually implementing Protocol

`EndOfStream`

The end of the stream was encountered before a complete value was read.

Note that this error condition may also be represented as a ReadError::Io with kind UnexpectedEof.

`FloatNotFinite`

Available on crate feature serde_json only.

`Io(Arc<Error>)`

`ReadNever`

Attempted to read an empty type

`Tungstenite(Arc<Error>)`

Available on crate feature tokio-tungstenite only.

`UnknownVariant8(u8)`

`UnknownVariant16(u16)`

`UnknownVariant32(u32)`

`UnknownVariant64(u64)`

`Utf8(FromUtf8Error)`

`Warp(Arc<Error>)`

Available on crate feature warp only.
