Struct emacs::CallEnv

pub struct CallEnv { /* fields omitted */ }

Like Env, but is available only in exported functions. This has additional methods to handle arguments passed from Lisp code.

Methods

impl CallEnv

pub unsafe fn new(     env: Env,     nargs: ptrdiff_t,     args: *mut emacs_value,     data: *mut c_void ) -> Self

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

pub fn raw_args(&self) -> &[emacs_value]

Important traits for Vec<u8>

impl Write for Vec<u8>

pub fn args(&self) -> Vec<Value>

pub fn get_arg(&self, i: usize) -> Value

pub fn parse_arg<T: FromLisp>(&self, i: usize) -> Result<T>

Methods from Deref<Target = Env>

pub fn raw(&self) -> *mut emacs_env

pub fn intern(&self, name: &str) -> Result<Value>

pub fn type_of(&self, value: Value) -> Result<Value>

pub fn call(&self, name: &str, args: &[Value]) -> Result<Value>

pub fn is_not_nil(&self, value: Value) -> bool

pub fn eq(&self, a: Value, b: Value) -> bool

pub fn list(&self, args: &[Value]) -> Result<Value>

pub fn provide(&self, name: &str) -> Result<Value>

pub fn message(&self, text: &str) -> Result<Value>

Trait Implementations

impl HandleCall for CallEnv

fn handle_call<'e, T, F>(&'e self, f: F) -> emacs_value where     F: Fn(&'e CallEnv) -> Result<T> + RefUnwindSafe,     T: IntoLisp<'e>,

impl Deref for CallEnv

This allows Env's methods to be called on a CallEnv.

type Target = Env

The resulting type after dereferencing.

fn deref(&self) -> &Env

Dereferences the value.

impl Debug for CallEnv

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

Formats the value using the given formatter.
