Enum ExprExtension 

#[non_exhaustive]
pub enum ExprExtension {}

Expression-language extensions.

Expression-level extensions add or modify functions, operators, or types beyond what the base revision provides. Today no such extensions exist — the “EXPR” extension in openjd-model gates whether the expression language is available at all, not which functions are registered once it is available. This enum is therefore defined as empty-but-#[non_exhaustive], reserving the API shape for the first expr-level extension.

Empty non-exhaustive enums are legal Rust and correctly express “values may exist in the future, none exist today.”

Implementations

impl ExprExtension

pub const ALL: &'static [ExprExtension]

All extension variants, in a stable order. Used by ExprProfile::latest to construct a profile with every expression-level extension enabled.

When a new variant is added, include it here. With no variants today the slice is empty; the constant still provides the contract that downstream code can rely on.

Trait Implementations

impl Clone for ExprExtension

fn clone(&self) -> ExprExtension

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprExtension

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

Formats the value using the given formatter.

impl Hash for ExprExtension

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 for ExprExtension

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