Enum NodePattern

pub enum NodePattern {
    Wildcard,
    Binder(WithMetaData<String>),
    Constructor(WithMetaData<NodeMetaIdentifier>, Vec<WithMetaData<NodeArgumentPattern>>),
}

NodePattern represents a pattern node in the AST It can either be a Wildcard, Binder or Constructor

Variants

Wildcard

Represents a wildcard pattern Example: match x with | _ => "wildcard" end

Binder(WithMetaData<String>)

Represents a binder pattern Example: match x with | a => "binder" end

Constructor(WithMetaData<NodeMetaIdentifier>, Vec<WithMetaData<NodeArgumentPattern>>)

Represents a constructor pattern Example: match x with | Cons a b => "constructor" end

Trait Implementations

impl AstVisitor for NodePattern

fn visit( &self, emitter: &mut dyn AstConverting, ) -> Result<TraversalResult, String>

impl Clone for NodePattern

fn clone(&self) -> NodePattern

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodePattern

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

Formats the value using the given formatter.

impl PartialEq for NodePattern

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

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