Enum MastNodeEntry 

#[repr(u8)]
pub enum MastNodeEntry {
    Join {
        left_child_id: u32,
        right_child_id: u32,
    },
    Split {
        if_branch_id: u32,
        else_branch_id: u32,
    },
    Loop {
        body_id: u32,
    },
    Block {
        ops_offset: u32,
    },
    Call {
        callee_id: u32,
    },
    SysCall {
        callee_id: u32,
    },
    Dyn = 6,
    Dyncall = 7,
    External = 8,
}

Fixed-width structural metadata for a serialized MastNode.

This is the random-access portion of the node table. Digests are intentionally modeled separately so the wire format can move them into dedicated sections.

Child indices for Join, Split, Loop, Call, and SysCall are stored inline so random access does not need any extra pointer chasing.

The serialized representation is always 8 bytes, which keeps the node-entry table fixed-width on the wire.

Implementations

impl MastNodeEntry

Constructors

pub const SERIALIZED_SIZE: usize = 8

Serialized byte size of one fixed-width MAST node entry.

pub fn new(mast_node: &MastNode, ops_offset: u32) -> MastNodeEntry

Constructs a new MastNodeEntry from a MastNode.

pub fn new_with_id_remap( mast_node: &MastNode, ops_offset: u32, id_remap: Option<&[u32]>, ) -> MastNodeEntry

Constructs a new MastNodeEntry from a MastNode, remapping child IDs when needed.

pub fn try_into_mast_node_builder( self, node_count: usize, basic_block_data_decoder: &BasicBlockDataDecoder<'_>, digest: Word, ) -> Result<MastNodeBuilder, DeserializationError>

Attempts to convert this MastNodeEntry into a MastNodeBuilder.

The node_count is the total expected number of nodes in the crate::mast::MastForest after deserialization.

impl MastNodeEntry

This impl block contains no public items.

Serialization helpers

impl MastNodeEntry

Deserialization helpers

pub fn decode_u32_payload(payload: u64) -> Result<u32, DeserializationError>

Decodes one u32 number from a 60-bit payload.

Returns an error if the payload doesn’t fit in a u32.

Trait Implementations

impl Clone for MastNodeEntry

fn clone(&self) -> MastNodeEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MastNodeEntry

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

Formats the value using the given formatter.

impl Deserializable for MastNodeEntry

fn min_serialized_size() -> usize

Returns the fixed serialized size: always 8 bytes (u64).

fn read_from<R>(source: &mut R) -> Result<MastNodeEntry, DeserializationError>

where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl PartialEq for MastNodeEntry

fn eq(&self, other: &MastNodeEntry) -> 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 Serializable for MastNodeEntry

fn write_into<W>(&self, target: &mut W)

where W: ByteWriter,

Serializes self into bytes and writes these bytes into the target.

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

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
