Struct ShadowFrame 

pub struct ShadowFrame {
    pub previous: *mut ShadowFrame,
    pub bytecode_pc: u32,
    pub module_id: u32,
    pub handles: *mut Value,
    pub handle_len: u16,
    /* private fields */
}

The register frame header shared by the interpreter and native code.

Layout is fixed and identical on every 64-bit target: previous at 0, bytecode_pc at 8, module_id at 12, handles at 16, and handle_len at 24, with explicit zeroed trailing padding. size = 32, align = 8. handles addresses exactly handle_len Values.

Fields

previous: *mut ShadowFrame

The caller’s frame, or null at the base of the stack.

bytecode_pc: u32

The current bytecode program counter.

module_id: u32

The dense module id of the executing function.

handles: *mut Value

The register array; register r[i] is handles[i].

handle_len: u16

The number of live registers, equal to function.register_count.

Implementations

impl ShadowFrame

pub fn new( previous: *mut ShadowFrame, bytecode_pc: u32, module_id: u32, handles: *mut Value, handle_len: u16, ) -> ShadowFrame

Builds a frame header with physically zeroed padding.
