Struct full_moon::ast::Block

pub struct Block<'a> { /* fields omitted */ }

A block of statements, such as in if/do/etc block

Implementations

impl<'a> Block<'a>

pub fn new() -> Self

Creates an empty block

pub fn iter_stmts(&self) -> impl Iterator<Item = &Stmt<'a>>

An iterator over the statements in the block, such as local foo = 1

pub fn last_stmts(&self) -> Option<&LastStmt<'a>>

👎 Deprecated since 0.5.0:

Use last_stmt instead

The last statement of the block if one exists, such as return foo Deprecated in favor of Block::last_stmt, the plural in last_stmts was a typo

pub fn last_stmt(&self) -> Option<&LastStmt<'a>>

The last statement of the block if one exists, such as return foo

pub fn with_stmts(
    self,
    stmts: Vec<(Stmt<'a>, Option<Cow<'a, TokenReference<'a>>>)>
) -> Self

Returns a new block with the given statements Takes a vector of statements, followed by an optional semicolon token reference

pub fn with_last_stmt(
    self,
    last_stmt: Option<(LastStmt<'a>, Option<Cow<'a, TokenReference<'a>>>)>
) -> Self

Returns a new block with the given last statement, if one is given Takes an optional last statement, with an optional semicolon

Trait Implementations

impl<'a> Clone for Block<'a>

fn clone(&self) -> Block<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Block<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Block<'a>

fn default() -> Block<'a>

Returns the "default value" for a type.

impl<'de: 'a, 'a> Deserialize<'de> for Block<'a>

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl<'a> Node<'a> for Block<'a>

fn start_position(&self) -> Option<Position>

The start position of a node. None if can't be determined

fn end_position(&self) -> Option<Position>

The end position of a node. None if it can't be determined

fn similar(&self, other: &Self) -> bool

Whether another node of the same type is the same as this one semantically, ignoring position

fn tokens<'b>(&'b self) -> Tokens<'a, 'b>ⓘ

Important traits for Tokens<'ast, 'b>

impl<'ast, 'b> Iterator for Tokens<'ast, 'b> type Item = Cow<'b, TokenReference<'ast>>;

The token references that comprise a node

fn range(&self) -> Option<(Position, Position)>

The full range of a node, if it has both start and end positions

fn surrounding_trivia<'b>(
    &'b self
) -> (Vec<Cow<'b, Token<'ast>>>, Vec<Cow<'b, Token<'ast>>>)

The tokens surrounding a node that are ignored and not accessible through the node's own accessors. Use this if you want to get surrounding comments or whitespace. Returns a tuple of the leading and trailing trivia.

impl<'a> Owned for Block<'a>

type Owned = Block<'static>

What an owned version of the object looks like. Usually contains a 'static lifetime.

fn owned(&self) -> Self::Owned

Returns an owned version of the object.

impl<'a> PartialEq<Block<'a>> for Block<'a>

fn eq(&self, other: &Block<'a>) -> bool
