Enum EventRegistrationError 

#[non_exhaustive]
pub enum EventRegistrationError {
    TypeConflict {
        name: String,
        existing: String,
        requested: String,
    },
    InvalidCapacity,
}

Event registration conflict or invalid retention input.

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.

TypeConflict

The same payload type or name was registered with incompatible options.

Fields

name: String

Registration name associated with the conflict.

existing: String

Existing entry name.

requested: String

Requested entry name.

InvalidCapacity

Bounded retention capacity must be nonzero.
