Struct RowKey

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

The key for a row in an architecture comparison table. All encodings that have the same RowKey should be grouped into the same row.

Implementations

impl RowKey

pub fn new_from_iter( num_arches: usize, exists: impl Iterator<Item = bool>, check_equal: impl FnMut(usize, usize) -> bool, ) -> RowKey

Creates a new RowKey.

The exists iterator should yield num_arches bools that determine whether the instructions exist for that architecture.

The check_equal function should return true if the semantics for the two architectures (passed as indices) are equal. check_equal should return false if the instructions do not exist on one of the two architectures, but true if they do not exist on both architectures.

pub fn repr(&self) -> u64

An u64 representation of the RowKey.

pub fn implementation_indices( &self, num_arches: usize, ) -> impl Iterator<Item = Option<usize>> + '_

Returns an iterator that yields the smallest architecture index that has equivalent semantics, for each architecture.

pub fn extract_sets(&self, num_arches: usize) -> (Vec<Vec<usize>>, Vec<usize>)

Extracts sets of equivalent semantics. Returns (equivalent_sets, missing), where equivalent_sets is a Vec containing one or more sets of architectures with equivalent semantics, and missing is a set of architectures on which the instructions described by this RowKey do not exist.

Trait Implementations

impl Clone for RowKey

fn clone(&self) -> RowKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowKey

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

Formats the value using the given formatter.

impl Hash for RowKey

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 RowKey

fn cmp(&self, other: &RowKey) -> 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 RowKey

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

impl PartialOrd for RowKey

fn partial_cmp(&self, other: &RowKey) -> 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.
