Struct full_moon::ast::Block

pub struct Block { /* private fields */ }

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

Implementations

impl Block

pub fn new() -> Self

Creates an empty block

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

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

Note that this does not contain the final statement which can be attained via Block::last_stmt.

pub fn stmts_with_semicolon( &self ) -> impl Iterator<Item = &(Stmt, Option<TokenReference>)>

An iterator over the statements in the block, including any optional semicolon token reference present

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

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

pub fn last_stmt_with_semicolon( &self ) -> Option<&(LastStmt, Option<TokenReference>)>

The last statement of the block if on exists, including any optional semicolon token reference present

pub fn with_stmts(self, stmts: Vec<(Stmt, Option<TokenReference>)>) -> 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, Option<TokenReference>)> ) -> 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 Clone for Block

fn clone(&self) -> Block

Returns a copy 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 Default for Block

fn default() -> Block

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Block

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

Deserialize this value from the given Serde deserializer.

impl Display for Block

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

Formats the value using the given formatter.

impl Node for Block

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<'a>(&'a self) -> Tokens<'a>

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(&self) -> (Vec<&Token>, Vec<&Token>)

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 PartialEq for Block

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Block

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
