Expand description
A list specifying general categories of errors.
This list is intended to grow over time and it is not recommended to exhaustively match against it.
Variants (Non-exhaustive)§
This enum is marked as 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.
VariablesCouldNotBeUpdated
The specified variable could not be updated.
VariableNotFound
The requested variable could not be found.
VariableAlreadyAdded
The variable with this name was already added.
FileWriteFailed
The resp. file could not be opened for writing.
FileReadFailed
The resp. file could not be opened for reading.
TreeIsNotConstant
The queried tree is not a constant.
