Expand description

A piece of error information

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.

`None`

ContextKind is self-sufficient, no additional information needed

`Bool(bool)`

A single value

`String(String)`

A single value

`Strings(Vec<String>)`

Many values

`Number(isize)`

A single value
