Struct EndpointDef 

pub struct EndpointDef {
    pub entry_pc: u64,
    pub stack_top: u64,
    pub arg_cnode_slot: SlotIdx,
    pub arg_cnode_size: u8,
    pub initial_regs: [u64; 13],
}

Endpoint definition. Dense initial_regs array; index i corresponds to PVM register φ[i]. 0 is “use default” (same semantics as the spec’s old BTreeMap<u8, u64> when the key is absent).

Fields

entry_pc: u64

stack_top: u64

arg_cnode_slot: SlotIdx

arg_cnode_size: u8

initial_regs: [u64; 13]

Implementations

impl EndpointDef

pub const fn empty() -> Self

Empty endpoint — entry_pc == 0 is the canonical sentinel for “not defined” (since a real entry PC is never zero — PC 0 is reserved as the fallback PC in our convention).

Trait Implementations

impl Clone for EndpointDef

fn clone(&self) -> EndpointDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EndpointDef

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

Formats the value using the given formatter.

impl Decode for EndpointDef

fn is_ssz_fixed_len() -> bool

true iff this type is fixed-length.

fn ssz_fixed_len() -> usize

Number of bytes this type occupies in the fixed-length portion of a container encoding. Variable-length types return BYTES_PER_LENGTH_OFFSET.

fn from_ssz_bytes(bytes: &[u8]) -> Result<Self, DecodeError>

Decode a full instance from bytes, rejecting trailing input.

impl Encode for EndpointDef

fn is_ssz_fixed_len() -> bool

true iff this type is fixed-length (no variable-length fields).

fn ssz_fixed_len() -> usize

Number of bytes this type occupies in the fixed-length portion of a container encoding. For variable-length types this returns BYTES_PER_LENGTH_OFFSET (i.e. the size of the offset slot).

fn ssz_bytes_len(&self) -> usize

Total size of self when serialized.

fn ssz_append(&self, buf: &mut Vec<u8>)

Append the encoding of self to buf.

fn is_basic_type() -> bool

true for “basic” SSZ types (uintN, bool), which pack adjacent elements into shared 32-byte chunks for merkleization. Composite types (containers, lists, structs) return false (the default).

fn as_ssz_bytes(&self) -> Vec<u8>

Serialize into a fresh Vec<u8> allocated through the global allocator.

impl HashTreeRoot for EndpointDef

fn hash_tree_root<__D: Digest<OutputSize = U32>>(&self) -> [u8; 32]

Compute the hash tree root using D as the underlying hash.

impl PartialEq for EndpointDef

fn eq(&self, other: &EndpointDef) -> 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.
