Struct ParentChainDepth 

pub struct ParentChainDepth {
    pub schema_version: u16,
    pub depth: u8,
}

Cached parent-chain depth — enables O(1) cycle / depth check (E-space-4). Monotone, computed from parent’s depth + 1 at spawn.

Fields

schema_version: u16

Wire-level schema version tag.

depth: u8

Depth (0 = root, max MAX_SPACE_DEPTH).

Trait Implementations

impl ArkheComponent for ParentChainDepth

const TYPE_CODE: u32 = 197122u32

Globally stable dispatch code within the runtime TypeCode registry.

const SCHEMA_VERSION: u16 = 1u16

Monotone schema version. Bump on field addition (#[serde(default)] paired); field removal / reorder forbidden.

fn type_code() -> TypeCode

TypeCode wrapper convenience.

fn approx_size(&self) -> usize

Approximate payload size for quota tracking. Default returns size_of::<Self>(); override for bytes::Bytes-carrying Components.

impl Clone for ParentChainDepth

fn clone(&self) -> ParentChainDepth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParentChainDepth

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ParentChainDepth

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ParentChainDepth

fn eq(&self, other: &ParentChainDepth) -> 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 Serialize for ParentChainDepth

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
