Trait Implementations

impl Clone for Statement

fn clone(&self) -> Statement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Statement

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

Formats the value using the given formatter.

impl From<AssertStatement> for Statement

fn from(value: AssertStatement) -> Self

Converts to this type from the input type.

impl From<AssignStatement> for Statement

fn from(value: AssignStatement) -> Self

Converts to this type from the input type.

impl From<Block> for Statement

fn from(value: Block) -> Self

Converts to this type from the input type.

impl From<ConditionalStatement> for Statement

fn from(value: ConditionalStatement) -> Self

Converts to this type from the input type.

impl From<ConstDeclaration> for Statement

fn from(value: ConstDeclaration) -> Self

Converts to this type from the input type.

impl From<DefinitionStatement> for Statement

fn from(value: DefinitionStatement) -> Self

Converts to this type from the input type.

impl From<ExpressionStatement> for Statement

fn from(value: ExpressionStatement) -> Self

Converts to this type from the input type.

impl From<IterationStatement> for Statement

fn from(value: IterationStatement) -> Self

Converts to this type from the input type.

impl Node for Statement

fn span(&self) -> Span

Returns the span of the node.

impl PartialEq for Statement

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

Tests for self and other values to be equal, and is used by ==.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
