Struct Block

pub struct Block {
    pub statements: Vec<(Pointer<Statement>, Option<Token>)>,
    pub last_statement: Option<(Pointer<TerminationStatement>, Option<Token>)>,
}

A block of code that represents a single scope (and nested ones).

Fields

statements: Vec<(Pointer<Statement>, Option<Token>)>

The tokens in the of this block only. Parent blocks’ tokens won’t be included. The optional Token is the optional semicolon after the statement.

last_statement: Option<(Pointer<TerminationStatement>, Option<Token>)>

The last statement (aka termination statement) of this scope. The optional Token is the optional semicolon after the statement.

Implementations

impl Block

pub fn is_empty(&self) -> bool

Whether or not this block is empty.

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 GetRange for Block

fn get_range(&self) -> Result<Range, GetRangeError>

Get the range of the node. This will only fail if Cst.status is AstStatus::HasErrors.

impl Hash for Block

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

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 Ord for Block

fn cmp(&self, other: &Block) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: MatchesToken> ParseWithArgs<T> for Block

fn parse_with( token: Token, lexer: &mut Lexer<'_>, errors: &mut Vec<ParseError>, stop_at: T, ) -> Option<Self>

Try parsing the current item, starting from the passed token with the passed arguments.

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.

impl PartialOrd for Block

fn partial_cmp(&self, other: &Block) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Print for Block

fn print(&self) -> String

Prints the whole token including all surrounding spaces.

impl Eq for Block

impl StructuralPartialEq for Block
