A binary operator. Spelling, wire name, and precedence live here so no consumer compares operator text.

Implementations

impl BinaryOperator

pub const ALL: [BinaryOperator; 18]

pub const fn symbol(self) -> &'static str

The operator as written in Harn source.

pub const fn wire_name(self) -> &'static str

The stable identifier used by AST JSON and other wire projections. It equals Self::symbol except that not in is spelled not_in.

pub fn from_wire_name(name: &str) -> Option<Self>

Resolve a wire name produced by Self::wire_name.

pub const fn precedence(self) -> Precedence

pub const fn continues_across_newline(self) -> bool

Whether a line break may precede the operator inside an expression.

- must not, so a line that starts with -x remains a new statement; in and not in must not, so a for x in header cannot be split.

pub const fn is_compound_assignable(self) -> bool

The operator a compound assignment (+=, -=, …) applies.

pub const fn is_comparison(self) -> bool

Operators whose result is always a boolean.

pub const fn is_logical(self) -> bool

pub const fn is_arithmetic(self) -> bool
