Struct SequencePointer 

Source 
pub struct SequencePointer(/* private fields */);
Expand description

A pointer that can advance through sibling sequence IDs.

SequencePointer is the only mechanism for creating new SequenceIds within a universe.

Implementations§

Source§

impl SequencePointer

Source

pub fn split(self) -> (SequencePointer, SequencePointer)

Splits this pointer into two, where the second is strictly greater than the first.

Source

pub fn split_off(&mut self) -> SequencePointer

Split off a pointer to appear before the current one.

The current pointer is advanced to the next sibling, and we return a new pointer.

Source

pub fn advance(&mut self) -> SequenceId

Advances to the next sibling sequence and returns the current one.

§Ownership

This method requires &mut self because it advances the internal state to point to the next sibling position.

Source

pub fn downgrade(self) -> SequenceId

Converts this pointer into its current SequenceId, consuming the pointer.

This method is useful when you want to access the current SequenceId without advancing to the next sibling. Once downgraded, you cannot create additional siblings from this pointer.
