Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bind

pat <- expr

Fields

pat: Pat

Pattern before <-.

expr: Expr

Expression after <-.

pos: Pos

Position of the statement’s first token.

span: Span

Span of the whole bind statement.

Let

let x = e (no in) inside a do block.

Fields

bindings: Vec<Binding>

Let bindings in source order.

pos: Pos

Position of the let token.

span: Span

Span of the whole let statement.

Expr

Bare expression statement.

Fields

expr: Expr

Statement expression.

pos: Pos

Position of the expression’s first token.

span: Span

Span of the expression statement.

Trait Implementations

impl Clone for DoStmt

fn clone(&self) -> DoStmt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DoStmt

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

Formats the value using the given formatter.

impl Eq for DoStmt

impl PartialEq for DoStmt

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