Struct VariablePattern

pub struct VariablePattern {
    pub name: Option<String>,
    pub type_id: Option<String>,
}

A variable identifier with an optional type annotation.

If the name of the identifier happens to be a single underscore character, the variable is considered nameless and no destructuring will take place.

Fields

fn clone(&self) -> VariablePattern

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl Hash for VariablePattern

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl PartialEq for VariablePattern

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