}

Represents a compiled bytecode function or expression.

Fields

name: Option<Name>

Code object name, if present; top-level expressions and lambda code values do not have a name.

consts: Box<[Value]>

Const values referenced in bytecode

code: Box<[u8]>

Function body bytecode

kw_params: Box<[Name]>

Names of keyword parameters accepted in the order in which they are expected.

n_params: u32

Number of positional parameters accepted; this includes optional parameters, but excludes keyword and rest parameters, if accepted. Optional parameter values may be Unbound.

req_params: u32

Number of positional parameters which must not be Unbound.

flags: u32

Miscellaneous flags; see code_flags for bit flag values.

doc: Option<String>

Optional documentation string

Methods

impl Code

fn arity(&self) -> Arity

Returns the computed arity of the compiled function.

fn has_rest_params(&self) -> bool

Returns whether the function accepts a rest parameter.

fn has_kw_params(&self) -> bool

Returns whether the function accepts one or more keyword parameters.

fn is_trivial(&self) -> bool

Returns whether all bytecode instructions can be executed without side effects.

Such a code object typically results from compilation of compile-time operators.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Code

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Code

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.
