Struct DuplicateMethodError 

#[non_exhaustive]
pub struct DuplicateMethodError {
    pub method: String,
}

Returned by Dispatcher::try_register when a handler is already registered under the requested method name.

Added in bd:JMAP-jfia.4 alongside try_register to make the duplicate-registration foot-gun explicit at the call site rather than silently dropping a binding.

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.

method: String

The method name that was already registered.

Trait Implementations

impl Clone for DuplicateMethodError

fn clone(&self) -> DuplicateMethodError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DuplicateMethodError

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

Formats the value using the given formatter.

impl Display for DuplicateMethodError

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

Formats the value using the given formatter.

impl Eq for DuplicateMethodError

impl Error for DuplicateMethodError

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 PartialEq for DuplicateMethodError

fn eq(&self, other: &DuplicateMethodError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
