impl OptPersons for OptMappedPersons

fn author_id(&self, node: NodeId) -> PropertiesResult<'_, Option<u32>, Self>

Returns None if out of bounds, Some(u32::MAX) if the node has no author

fn committer_id(&self, node: NodeId) -> PropertiesResult<'_, Option<u32>, Self>

Returns None if out of bounds, Some(u32::MAX) if the node has no committer

impl PropertiesBackend for OptMappedPersons

type DataFilesAvailability = OptionalDataFiles

fn map_if_available<T, U>( v: <Self::DataFilesAvailability as DataFilesAvailability>::Result<'_, T>, f: impl FnOnce(T) -> U, ) -> <Self::DataFilesAvailability as DataFilesAvailability>::Result<'_, U>

Applies the given function f to the value v if the value is available

fn zip_if_available<'err, T1, T2>( v1: <Self::DataFilesAvailability as DataFilesAvailability>::Result<'err, T1>, v2: <Self::DataFilesAvailability as DataFilesAvailability>::Result<'err, T2>, ) -> <Self::DataFilesAvailability as DataFilesAvailability>::Result<'err, (T1, T2)>

Returns (v1, v2) if both are available, or an error otherwise
