Implementations

impl ContextId

pub fn combine(
    &self,
    other: ContextId
) -> Result<ContextId, IncompatibleContextIds>

Attempts to combine two ContextIds, or returns an [IncompatibleContextIds] error when they are incompatible.

Two ContextIds are compatible if:

• Either or both ContextIds are ContextId::Any. In this case ContextId::Any will be returned.
• Both are ContextId::Id and the two IDs are identical. In this case [ContextId::Id(id)] will be returned, where id is the ID shared by both ContextIds.

Two ContextIds are incompatible if:

• Both are ContextId::Id and the two IDs are not identical. In this case an [IncompatibleContextIds] error will be returned.
