pub struct StmtBlock { /* private fields */ }

(internals) A scoped block of statements. Exported under the internals feature only.

Implementations

impl StmtBlock

pub const NONE: Self = _

pub fn new_with_span( statements: impl IntoIterator<Item = Stmt>, span: Span ) -> Self

Create a new StmtBlock.

pub const fn empty(pos: Position) -> Self

Create an empty StmtBlock.

pub fn is_empty(&self) -> bool

Returns true if this statements block contains no statements.

pub fn len(&self) -> usize

Number of statements in this statements block.

pub fn statements(&self) -> &[Stmt]

Get the statements of this statements block.

pub fn statements_mut(&mut self) -> &mut SmallVec<[Stmt; 8]>

Get the statements of this statements block.

pub fn iter(&self) -> impl Iterator<Item = &Stmt>

Get an iterator over the statements of this statements block.

pub const fn position(&self) -> Position

Get the start position (location of the beginning {) of this statements block.

pub const fn end_position(&self) -> Position

Get the end position (location of the ending }) of this statements block.

pub const fn span(&self) -> Span

Get the positions (locations of the beginning { and ending }) of this statements block.

pub const fn span_or_else( &self, def_start_pos: Position, def_end_pos: Position ) -> Span

Get the positions (locations of the beginning { and ending }) of this statements block or a default.

pub fn set_position(&mut self, start_pos: Position, end_pos: Position)

Set the positions of this statements block.

Trait Implementations

impl AsMut<[Stmt]> for StmtBlock

fn as_mut(&mut self) -> &mut [Stmt]

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<[Stmt]> for StmtBlock

fn as_ref(&self) -> &[Stmt]

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<[Stmt]> for StmtBlock

fn borrow(&self) -> &[Stmt]

Immutably borrows from an owned value.

impl Clone for StmtBlock

fn clone(&self) -> StmtBlock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StmtBlock

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

Formats the value using the given formatter.

impl Default for StmtBlock

fn default() -> StmtBlock

Returns the “default value” for a type.

impl Extend<Stmt> for StmtBlock

fn extend<T: IntoIterator<Item = Stmt>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

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<'a> IntoIterator for &'a StmtBlock

type Item = &'a Stmt
