Struct rhai::OpAssignment

pub struct OpAssignment { /* private fields */ }

(internals) An op-assignment operator. Exported under the internals feature only.

This type may hold a straight assignment (i.e. not an op-assignment).

Implementations

impl OpAssignment

pub const fn new_assignment(pos: Position) -> Self

Create a new OpAssignment that is only a straight assignment.

pub fn is_op_assignment(&self) -> bool

Is this an op-assignment?

pub fn get_op_assignment_info( &self ) -> Option<(u64, u64, &Token, &'static str, &Token, &'static str)>

Get information if this OpAssignment is an op-assignment.

Returns ( hash_op_assign, hash_op, op_assign, op_assign_syntax, op, op_syntax ):

• hash_op_assign: Hash of the op-assignment call.
• hash_op: Hash of the underlying operator call (for fallback).
• op_assign: Op-assignment operator.
• op_assign_syntax: Syntax of op-assignment operator.
• op: Underlying operator.
• op_syntax: Syntax of underlying operator.

pub const fn position(&self) -> Position

Get the position of this OpAssignment.

pub fn new_op_assignment(name: &str, pos: Position) -> Self

Create a new OpAssignment.

Panics

Panics if the name is not an op-assignment operator.

pub fn new_op_assignment_from_token(op_assign: Token, pos: Position) -> Self

Create a new OpAssignment from a Token.

Panics

Panics if the token is not an op-assignment operator.

pub fn new_op_assignment_from_base(name: &str, pos: Position) -> Self

Create a new OpAssignment from a base operator.

Panics

Panics if the name is not an operator that can be converted into an op-operator.

pub fn new_op_assignment_from_base_token(op: &Token, pos: Position) -> Self

Convert a Token into a new OpAssignment.

Panics

Panics if the token is cannot be converted into an op-assignment operator.

Trait Implementations

impl Clone for OpAssignment

fn clone(&self) -> OpAssignment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpAssignment

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

Formats the value using the given formatter.

impl Hash for OpAssignment

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<OpAssignment> for OpAssignment

fn eq(&self, other: &OpAssignment) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
