Struct OperDefTab 

pub struct OperDefTab { /* private fields */ }

Container for operator definitions indexed by Fixity.

Each entry in the internal array corresponds to one fixity variant (function, prefix, infix, or postfix).

Implementations

impl OperDefTab

pub const fn new() -> Self

Creates a new, empty OperDefTab with all fixity slots unset.

Each entry in the table corresponds to a Fixity variant (fun, prefix, infix, or postfix), all initialized to None.

pub fn is_fun(&self) -> bool

Returns true if this table defines a function (fun) operator.

pub fn is_oper(&self) -> bool

Returns true if this table defines at least one operator fixity.

pub fn get_op_def(&self, fixity: Fixity) -> Option<&OperDef>

Retrieves the operator definition for the given Fixity, if present.

Trait Implementations

impl Clone for OperDefTab

fn clone(&self) -> OperDefTab

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperDefTab

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

Formats the value using the given formatter.

impl Index<Fixity> for OperDefTab

fn index(&self, i: Fixity) -> &Self::Output

Indexes the table by Fixity, returning the corresponding definition.

Panics

Panics if the fixity discriminant is out of range (should never occur).

type Output = Option<OperDef>

The returned type after indexing.

impl IndexMut<Fixity> for OperDefTab

fn index_mut(&mut self, i: Fixity) -> &mut Self::Output

Mutable indexing by Fixity, allowing modification of the definition.

Panics

Panics if the fixity discriminant is out of range (should never occur).
