Enum WorkflowContextError 

#[non_exhaustive]
pub enum WorkflowContextError {
    MissingKey,
    Parse(ParseIntError),
    DuplicateEntry(MetadataError),
}

Represents an invalid WorkflowContext state

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.

MissingKey

An entry for the key is missing

Parse(ParseIntError)

Could not parse the value provided

DuplicateEntry(MetadataError)

Duplicate entry

Trait Implementations
