Enum ForkAction

pub enum ForkAction {

    MoveToSiblingBranch(u32),

}

Deterministic branch traversal and navigation actions for moving across the local fork graph.

Variants

MoveToParentBranchBack(u32)

Move upward N parent branches.

Before: A -> B -> C |– C’ |– D’ ^

Example: MoveToParentBranchBack(2)

After: A -> B -> C ^

MoveToParentBranch

Move to the direct parent branch.

Before: A -> B -> C |– C’ ^

After: A -> B -> C ^

MoveToChildBranch(u32)

Move forward into the N-th child branch if it exists.

Before: A -> B -> C ^ |– C’ |– C’’

Example: MoveToChildBranch(1)

After: A -> B -> C |– C’’ ^

MoveToNextChildBranch

Move forward into the first child branch if it exists.

Before: A -> B -> C ^ |– C’

After: A -> B -> C |– C’ ^

Deterministic traversal: always child index 0.

MoveToSiblingBranch(u32)

Move to a specific sibling branch index.

If unavailable, remain on current branch.

Before: A -> B -> C |– D | ^ |– D’

After: A -> B -> C |– D |– D’ ^

MoveToNextSiblingBranch

Move to the next sibling branch if it exists.

Before: A -> B -> C |– D | ^ |– D’

After: A -> B -> C |– D |– D’ ^

MoveToPreviousSiblingBranch

Move to the previous sibling branch if it exists.

Before: A -> B -> C |– D |– D’ ^

After: A -> B -> C |– D | ^ |– D’

MoveToRootBranch

Jump to the oldest reachable ancestry root.

This may be true genesis ancestry or a synthetic recovery root depending on recovery history.

Before: A -> B -> C |– C’ -> D’ ^

After: A ^

Trait Implementations

impl Clone for ForkAction

fn clone(&self) -> ForkAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForkAction

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

Formats the value using the given formatter.

impl Ord for ForkAction

fn cmp(&self, other: &ForkAction) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ForkAction

fn eq(&self, other: &ForkAction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ForkAction

fn partial_cmp(&self, other: &ForkAction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
