Enum MatchPattern 

pub enum MatchPattern {
    ConstSymbol(String),
    ConstNumber(f64),
    Wildcard,
}

A pattern used in a TLExpr::Match arm.

Patterns are intentionally minimal (Design A):

• ConstSymbol(String) — match a symbol literal by name.
• ConstNumber(f64) — match a numeric literal by value.
• Wildcard — match anything; must be the last arm in a Match.

Variants

ConstSymbol(String)

Match a symbol literal (lowered to Eq(scrutinee, SymbolLiteral(s))).

ConstNumber(f64)

Match a numeric literal (lowered to Eq(scrutinee, Constant(n))).

Wildcard

Wildcard — matches anything. Must be the last arm.

Trait Implementations

impl Clone for MatchPattern

fn clone(&self) -> MatchPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MatchPattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MatchPattern

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MatchPattern

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

Formats the value using the given formatter.

impl PartialEq for MatchPattern

fn eq(&self, other: &MatchPattern) -> 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 Serialize for MatchPattern

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
