Struct GraphTopology 

pub struct GraphTopology<'view> {
    pub forward: ForwardCsr<'view>,
    pub inbound: InboundCsc<'view>,
}

Both topology views borrowing the same snapshot backing.

Fields

forward: ForwardCsr<'view>

Forward CSR over outgoing edges.

inbound: InboundCsc<'view>

Inbound CSC over predecessor lists.

Implementations

impl<'view> GraphTopology<'view>

pub fn open(snapshot: &Snapshot<'view>) -> Result<Self, PostgresGraphError>

Opens both layouts from validated snapshot bytes.

Errors

Returns PostgresGraphError when metadata, sections, or cross-layout counts disagree.

Performance

This function is O(s + n + m).

Trait Implementations

impl<'view> Clone for GraphTopology<'view>

fn clone(&self) -> GraphTopology<'view>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'view> Copy for GraphTopology<'view>

impl<'view> Debug for GraphTopology<'view>

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

Formats the value using the given formatter.

impl<'yoke> Yokeable<'yoke> for GraphTopology<'static>

type Output = GraphTopology<'yoke>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'yoke self) -> &'yoke Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(from: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'yoke mut self, f: F)

where F: 'static + for<'_yoke> FnOnce(&'_yoke mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.
