Struct trust_dns_proto::error::ProtoError

#[non_exhaustive]
pub struct ProtoError {
    pub kind: Box<ProtoErrorKind>,
    pub backtrack: Option<ExtBacktrace>,
}

The error type for errors that get returned in the crate

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: Box<ProtoErrorKind>

Kind of error that ocurred

backtrack: Option<ExtBacktrace>

This is supported on crate feature backtrace only.

Backtrace to the source of the error

Implementations

impl ProtoError

pub fn kind(&self) -> &ProtoErrorKind

Get the kind of the error

pub fn is_busy(&self) -> bool

If this is a ProtoErrorKind::Busy

Trait Implementations

impl Clone for ProtoError

fn clone(&self) -> ProtoError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProtoError

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

Formats the value using the given formatter.

impl Display for ProtoError

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

Formats the value using the given formatter.

impl Error for ProtoError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
