Struct IoError 

pub struct IoError { /* private fields */ }

A failure that originated below SMTP, in the transport (TCP, TLS, the runtime’s socket API).

Adapter crates (e.g. wasm-smtp-cloudflare) convert their runtime-specific errors into this type at the transport boundary. The conversion is lossy by design: it preserves a human-readable message but discards the original type, which keeps adapter-specific types out of the core public API.

Implementations

impl IoError

pub fn new(message: impl Into<String>) -> Self

Construct from any Display-able message.

pub fn message(&self) -> &str

The human-readable description of the failure.

Trait Implementations

impl Debug for IoError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for IoError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for IoError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<IoError> for SmtpError

fn from(value: IoError) -> Self

Converts to this type from the input type.
