Struct HookId 

pub struct HookId(/* private fields */);

Opaque identifier of an externally implemented hook.

The IR deliberately cannot express arbitrary target code; a hook node defers one predicate or action to the evaluation context, which maps the id to grammar-specific behavior (a user trait method, or a runtime shim such as the conformance suite’s evaluation-reporting predicates).

Implementations

impl HookId

pub const fn new(index: u32) -> Self

Builds a hook id from a producer-assigned side-table index.

pub const fn index(self) -> usize

Position of this hook in the producer’s hook side table.

Trait Implementations

impl Clone for HookId

fn clone(&self) -> HookId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HookId

impl Debug for HookId

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

Formats the value using the given formatter.

impl Eq for HookId

impl Hash for HookId

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 Ord for HookId

fn cmp(&self, other: &HookId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for HookId

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for HookId

fn partial_cmp(&self, other: &HookId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
