Enum Pattern 

pub enum Pattern {
    Variant(String),
    VariantWithBindings {
        name: String,
        bindings: Vec<String>,
    },
}

A pattern in a match expression For Phase 1: just the variant name (stack-based matching) Later phases will add field bindings: Get { chan }

Variants

Variant(String)

Match a variant by name, pushing all fields to stack Example: Get -> pushes response-chan to stack

VariantWithBindings

Match a variant with named field bindings (Phase 5) Example: Get { chan } -> binds chan to the response-chan field

Fields

name: String

bindings: Vec<String>

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate 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 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.
