Enum SourceError 

pub enum SourceError {
    Transport,
    Framing(FramingError),
}

Why the next inbound frame did not arrive.

Domain types only. An adapter maps its own io::Error into Transport at the boundary, so nothing in application/ names a type from a runtime or from the operating system.

Variants

Transport

The transport could not read.

Carries nothing, and that is the point. Every adapter has its own failures — a broken pipe, a reset, a child that exited, an HTTP body that ended early — and rendering any of them into a String an implementor controls would put a peer’s bytes on the application layer’s error path for nothing. A caller that needs to know which failure maps its own.

Framing(FramingError)

The bytes on the wire were not a frame.

A peer that will not terminate its line, or that sent something that is not text, is a fact about the peer rather than about the pipe, and it is worth distinguishing from a transport that simply failed.

impl Eq for SourceError

impl Error for SourceError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
