Trait Implementations

impl<R: Debug> Debug for LinearSegment<R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<R: Read> Segment for LinearSegment<R>

type FactIndex = LinearFactIndex<R>

type Command<'a> = LinearCommand<'a> where R: 'a

fn index(&self) -> SegmentIndex

Returns the segment’s index.

fn head_id(&self) -> CmdId

Returns the ID of the head of the segment.

fn first_location(&self) -> Location

Returns the location of the first command.

fn policy(&self) -> PolicyId

Returns the id for the policy used for this segment.

fn prior(&self) -> Prior<Location>

Returns the prior segments for this segment.

fn get_command(&self, location: Location) -> Option<Self::Command<'_>>

Returns the command at the given location.

fn facts(&self) -> Result<Self::FactIndex, StorageError>

Get the fact index associated with this segment.

fn skip_list(&self) -> &[Location]

The skip list is a series of locations that can be safely jumped to when searching for a location. As long as the max cut of the location you’re jumping to is greater than or equal to the location you’re searching for you can jump to it and be guaranteed not to miss the location you’re searching for.

fn shortest_max_cut(&self) -> MaxCut

The shortest max cut for this segment.

fn longest_max_cut(&self) -> Result<MaxCut, StorageError>

The longest max cut for this segment.

fn get_from(&self, location: Location) -> Vec<Self::Command<'_>>

Returns an iterator of commands starting at the given location.

fn get_by_address(&self, address: Address) -> Option<Location>

Returns the location of the command with the given address from within this segment.

fn head_location(&self) -> Result<Location, StorageError>

Returns the location of the head of the segment.

fn head_address(&self) -> Result<Address, StorageError>

Returns the address of the head of the segment.

fn previous(&self, location: Location) -> Option<Location>

Walks a location toward init if it would still point within this segment.
