Struct Trampoline 

pub struct Trampoline {
    pub segment: u8,
    pub next: StepId,
}

Trampoline instruction for universal entry.

Like Call, but the target comes from VM context (external parameter) rather than being encoded in the instruction. Used at address 0 for the entry preamble: Obj → Trampoline → EndObj → Accept.

Fields

segment: u8

Segment index (0-3).

next: StepId

Return address (where to continue after entrypoint returns).

Implementations

impl Trampoline

pub fn new(next: StepId) -> Self

Create a new Trampoline instruction.

pub fn to_bytes(&self) -> [u8; 8]

Encode to 8-byte bytecode.

Header byte layout: segment(2) | node_kind(2) | opcode(4)

pub fn next(&self) -> StepId

Trait Implementations

impl Clone for Trampoline

fn clone(&self) -> Trampoline

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Trampoline

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

Formats the value using the given formatter.

impl PartialEq for Trampoline

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