Implementations

impl Pattern

pub fn parse(i: &str) -> Result<Self, ErrorTree<String>>

fn len(&self) -> usize

pub fn matches(&self, ctx: &TranslatedCrate, name: &Name) -> bool

pub fn matches_with_generics( &self, ctx: &TranslatedCrate, name: &Name, args: &GenericArgs, ) -> bool

pub fn matches_ty(&self, ctx: &TranslatedCrate, ty: &Ty) -> bool

pub fn matches_const(&self, _ctx: &TranslatedCrate, _c: &ConstGeneric) -> bool

pub fn compare(&self, other: &Self) -> Ordering

Compares two patterns that match the same name, in terms of precision. A pattern that is fully included in another (i.e. matches a subset of values) is considered “less precise”. Returns nonsense if the patterns don’t match the same name.

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Pattern

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Pattern

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

Formats the value using the given formatter.

impl FromStr for Pattern

The entry point for this module: parses a string into a Pattern.

type Err = GenericErrorTree<String, &'static str, &'static str, Box<dyn Error + Send + Sync>>

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Ord for Pattern

Orders patterns by precision: the maximal pattern is the most precise. COmparing patterns only makes sense if they match the same name.

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Pattern

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

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

impl Serialize for Pattern

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
