Struct FnFrameEnv 

pub struct FnFrameEnv { /* private fields */ }

An implementation of FunctionFrameEnvironment

Implementations

impl FnFrameEnv

pub fn new() -> Self

Create a new environment instance.

Trait Implementations

impl Clone for FnFrameEnv

fn clone(&self) -> FnFrameEnv

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FnFrameEnv

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

Formats the value using the given formatter.

impl Default for FnFrameEnv

fn default() -> FnFrameEnv

Returns the “default value” for a type.

impl FunctionFrameEnvironment for FnFrameEnv

fn push_fn_frame(&mut self)

Denote that a new function has been invoked and is currently executing.

Panics

Panics if the number of pushed frames overflows a usize.

fn pop_fn_frame(&mut self)

Denote that a function has completed and is no longer executing.

fn is_fn_running(&self) -> bool

Determines if there is at least one function being currently executed.

impl PartialEq for FnFrameEnv

fn eq(&self, other: &FnFrameEnv) -> 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 SubEnvironment for FnFrameEnv

fn sub_env(&self) -> Self

Create a new sub-environment, which starts out idential to its parent, but any changes on the new environment will not be reflected on the parent.

impl Copy for FnFrameEnv

impl Eq for FnFrameEnv
