Implementations

impl NativeFunction

pub fn new<S, AS, D, B>(name: S, argspec: AS, doc: D, body: B) -> NativeFunction

where S: Into<RcStr>, AS: Into<ArgSpec>, D: Into<DocStr>, B: Fn(&mut Globals, Vec<Value>, Option<HashMap<RcStr, Value>>) -> Result<Value, Error> + 'static,

pub fn name(&self) -> &RcStr

pub fn argspec(&self) -> &ArgSpec

pub fn doc(&self) -> &Option<RcStr>

pub fn apply( &self, globals: &mut Globals, args: Vec<Value>, kwargs: Option<HashMap<RcStr, Value>>, ) -> Result<Value, Error>

Trait Implementations

impl Debug for NativeFunction

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

Formats the value using the given formatter.

impl From<NativeFunction> for Value

fn from(f: NativeFunction) -> Value

Converts to this type from the input type.

impl PartialEq for NativeFunction

fn eq(&self, other: &NativeFunction) -> 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 PartialOrd for NativeFunction

fn partial_cmp(&self, other: &NativeFunction) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
