Struct Block 

pub struct Block {
    pub stmts: Vec<Stmt>,
    pub value: Option<Box<Expr>>,
    pub span: Span,
}

a { ... } block: a sequence of statements, optionally ending in a trailing expression with no ;. value is that trailing expression; None means the block’s value is void (it ended in a ;, or it was empty). a block is also an expression in this language – see Expr::Block.

Fields

stmts: Vec<Stmt>

the statements, in order.

value: Option<Box<Expr>>

the trailing expression (no terminating ;) that is the block’s value, or None for a void block.

span: Span

{ to }.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl PartialEq for Block

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