Struct sway_ir::metadata::MetadataIndex

pub struct MetadataIndex(pub Index);

! Associated metadata attached mostly to values. ! ! Each value (instruction, function argument or constant) has associated metadata which helps ! describe properties which aren’t required for code generation, but help with other ! introspective tools (e.g., the debugger) or compiler error messages. ! ! The metadata themselves are opaque to sway-ir and are represented with simple value types; ! integers, strings, symbols (tags) and lists.

Trait Implementations

impl Clone for MetadataIndex

fn clone(&self) -> MetadataIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataIndex

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

Formats the value using the given formatter.

impl Hash for MetadataIndex

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for MetadataIndex

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<MetadataIndex> for MetadataIndex

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<MetadataIndex> for MetadataIndex

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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