Struct Error 

pub struct Error { /* private fields */ }

Available on crate feature api only.

An error raised when encoding or decoding a message.

Implementations

impl Error

pub fn unsupported_format(&self) -> Option<Format>

Test if the error is caused by a format which is not supported, and if so return it.

pub fn unsupported_version(&self) -> Option<u32>

Test if the error is caused by a peer speaking a different version of the protocol, and if so return the version it stated.

A session between peers which do not agree on this is refused before either of them has acted on anything the other said, see the protocol version.

pub fn is_unknown_header(&self) -> bool

Test if the error is caused by a header this build does not know about.

A peer which writes one is speaking a protocol this build has never seen, which is never something to carry on through.

🔬This is a nightly-only experimental API. (error_generic_member_access)
