ActivateError

velesdb_core::collection::streaming::delta

Enum ActivateError 

Source 
#[non_exhaustive]
pub enum ActivateError {
    AlreadyActive,
}
Expand description

Error returned by DeltaBuffer::try_activate when activation is rejected.

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.
§

AlreadyActive

The buffer was not INACTIVE (it is ACTIVE or DRAINING), so a concurrent activation/drain already owns it. Signals a double-activation bug rather than a recoverable condition.

painted.fg(Color::White);

Set foreground color to white using white().

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
