Enum MatchKind

pub enum MatchKind {
    Attribute {
        macro_id: Option<AttributeId>,
    },
    Macro {
        parent_macro_id: Option<AttributeId>,
    },
}

The kind of attribute within the context of a match.

Variants

Attribute

A attribute.

Fields

macro_id: Option<AttributeId>

The location of the macro which referred to it the list with all in-order attributes and macros, or None if this is attribute wasn’t resolved.

Use Outcome::match_by_id() to retrieve the macro.

Macro

The attribute is a macro, which will resolve into one or more attributes or macros.

Fields

parent_macro_id: Option<AttributeId>

The location of the parent macro which referred to this one in the list with all in-order attributes and macros, or None if this is macro wasn’t resolved by another one.

Use Outcome::match_by_id() to retrieve the parent.

Implementations

impl MatchKind

pub fn source_id(&self) -> Option<AttributeId>

return the id of the macro that resolved us, or None if that didn’t happen.

Trait Implementations

impl Clone for MatchKind

fn clone(&self) -> MatchKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MatchKind

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

Formats the value using the given formatter.

impl Hash for MatchKind

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 MatchKind

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

fn eq(&self, other: &MatchKind) -> 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 MatchKind

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