Enum AssignTarget

pub enum AssignTarget {
    Symbol(LitSym),
    Index(Index),
    Func(FuncHeader),
}

An assignment target, such as x, list[0], or f(x).

Variants

Symbol(LitSym)

A symbol, such as x.

Index(Index)

A list index, such as list[0].

Func(FuncHeader)

A function header, such as f(x).

Implementations

impl AssignTarget

pub fn span(&self) -> Range<usize>

Returns the span of the assignment target.

pub fn is_func(&self) -> bool

Returns true if the assignment target is a function.

pub fn try_from_with_op(expr: Expr, op: &AssignOp) -> ParseResult<Self>

Tries to convert a general Expr into an AssignTarget. This is used when parsing assignment expressions, such as x = 1 or f(x) = x^2.

Trait Implementations

impl Clone for AssignTarget

fn clone(&self) -> AssignTarget

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AssignTarget

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

Formats the value using the given formatter.

impl Display for AssignTarget

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

Formats the value using the given formatter.

impl From<FuncHeader> for AssignTarget

fn from(func: FuncHeader) -> Self

Converts to this type from the input type.

impl From<Index> for AssignTarget

fn from(index: Index) -> Self

Converts to this type from the input type.

impl From<LitSym> for AssignTarget

fn from(symbol: LitSym) -> Self

Converts to this type from the input type.

impl Latex for AssignTarget

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

Format the value as LaTeX.

fn as_display(&self) -> LatexFormatter<'_, Self>

Wraps the value in a LatexFormatter, which implements Display.

impl<'source> Parse<'source> for AssignTarget

fn std_parse( input: &mut Parser<'source>, recoverable_errors: &mut Vec<Error>, ) -> Result<Self, Vec<Error>>

Parses a value from the given stream of tokens, advancing the stream past the consumed tokens if parsing is successful.

fn parse(input: &mut Parser<'source>) -> ParseResult<Self>

Parses a value from the given stream of tokens, advancing the stream past the consumed tokens if parsing is successful.

impl PartialEq for AssignTarget

fn eq(&self, other: &AssignTarget) -> 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.
