Enum VarPattern

pub enum VarPattern {
    Discard(Token),
    Glob(Token),
    Ident(Identifier),

}

Variants

Discard(Token)

Glob(Token)

Ident(Identifier)

Phi(Identifier)

Used when a different value is assigned in a branch other than Ident. (e.g. the else variable when a variable is defined with Python if-else) Not used in Erg mode at this time

List(VarListPattern)

e.g. [x, y, z] of [x, y, z] = [1, 2, 3]

Tuple(VarTuplePattern)

e.g. (x, y, z) of (x, y, z) = (1, 2, 3)

Record(VarRecordPattern)

DataPack(VarDataPackPattern)

Trait Implementations

impl Clone for VarPattern

fn clone(&self) -> VarPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VarPattern

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

Formats the value using the given formatter.

impl Display for VarPattern

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

Formats the value using the given formatter.

impl Hash for VarPattern

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 Locational for VarPattern

fn loc(&self) -> Location

NOTE: loc cannot be treated as a light method when self is a large grammatical element. If possible, delay the computation by passing &impl Locational or other means.

fn ln_begin(&self) -> Option<u32>

1-origin

fn ln_end(&self) -> Option<u32>

fn col_begin(&self) -> Option<u32>

0-origin

fn col_end(&self) -> Option<u32>

impl NestedDisplay for VarPattern

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

impl PartialEq for VarPattern

fn eq(&self, other: &VarPattern) -> 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.
