Enum MergeError 

#[non_exhaustive]
pub enum MergeError {
    UnknownSource {
        source_id: SourceId,
        num_sources: usize,
    },
    QueueFull {
        max_queued: usize,
    },
}

Errors ByteMerge::feed can return.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnknownSource

source is not one of 0..num_sources for this merge.

Fields

source_id: SourceId

The out-of-range source that was fed.

num_sources: usize

How many sources this merge was constructed with.

QueueFull

The bounded output queue already holds max_queued messages awaiting ByteMerge::poll; the call was rejected outright and nothing from it was buffered.

Fields

max_queued: usize

The configured queue bound.

Trait Implementations

impl Clone for MergeError

fn clone(&self) -> MergeError

impl Copy for MergeError

impl Debug for MergeError

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

impl Eq for MergeError

impl Error for MergeError

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 MergeError

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

Equality operator ==.

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

Inequality operator !=.
