}Expand description
Various kinds of errors that can occur in a milter application.
Variants
SocketConfig(CString)
Tuple Fields
0: CStringThe socket specification provided to the Milter could not be used.
TimeoutConfig(i32)
Tuple Fields
0: i32The timeout duration configuration parameter of the Milter is invalid.
SocketBacklogConfig(i32)
Tuple Fields
0: i32The socket backlog length configuration parameter of the Milter is
invalid.
Registration
Registration of the Milter’s configuration with libmilter failed.
Main
The libmilter library’s event loop (main function) exited with a
failure status.
CallbackPanic
The libmilter library’s event loop was shut down after a panic in a callback.
FailureStatus
A libmilter function returned the failure status code.
FfiCString(NulError)
Tuple Fields
0: NulErrorConversion to a C-style string at the FFI boundary (Rust/C) failed, with cause attached.
FfiInt(TryFromIntError)
Tuple Fields
Conversion to an integer type at the FFI boundary (Rust/C) failed, with cause attached.
FfiUtf8(Utf8Error)
Tuple Fields
0: Utf8ErrorConversion to a UTF-8 string at the FFI boundary (Rust/C) failed, with cause attached.
Custom(Box<dyn Error + Send + Sync>)
An unspecific error variant, with cause attached.
Examples
This variant is provided as a convenience; use it to propagate arbitrary errors out of a callback.
use milter::{Context, Error, Status};
use std::fs::File;
fn handle_data(_: Context<()>) -> milter::Result<Status> {
let _ = File::create("/tmp/archive").map_err(|e| Error::Custom(e.into()))?;
Ok(Status::Continue)
}Trait Implementations
Performs the conversion.
