Struct MemSegment 

pub struct MemSegment(/* private fields */);

Trait Implementations

impl Clone for MemSegment

fn clone(&self) -> MemSegment

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemSegment

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

Formats the value using the given formatter.

impl Deref for MemSegment

type Target = MemSegmentInner

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<MemSegmentInner> for MemSegment

fn from(segment: MemSegmentInner) -> Self

Converts to this type from the input type.

impl Segment for MemSegment

type FactIndex = MemFactIndex

type Command<'a> = &'a MemCommand

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<&MemCommand>

Returns the command at the given location.

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

The longest max cut for this segment.

fn shortest_max_cut(&self) -> MaxCut

The shortest max cut for 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 facts(&self) -> Result<Self::FactIndex, StorageError>

Get the fact index associated with 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.
