pub enum FlowExpression {
    ConnectionExpression(Box<ConnectionExpression>),
    BlockExpression(BlockExpression),
}

Implementations

impl FlowExpression

pub fn as_connection(&self) -> Option<&ConnectionExpression>

Get the expression as a ConnectionExpression.

pub const fn as_block(&self) -> Option<&BlockExpression>

Get the expression as a BlockExpression.

pub fn connection(expr: ConnectionExpression) -> Self

Make a new FlowExpression::ConnectionExpression from a ConnectionExpression.

pub const fn block(expr: BlockExpression) -> Self

Make a new FlowExpression::BlockExpression from a BlockExpression.

pub fn replace(&mut self, expr: Self)

Convenience method to replace the expression with a new one.

Trait Implementations

impl Clone for FlowExpression

fn clone(&self) -> FlowExpression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FlowExpression

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

Formats the value using the given formatter.

impl FromStr for FlowExpression

type Err = ParserError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq<FlowExpression> for FlowExpression

fn eq(&self, other: &FlowExpression) -> 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 FlowExpression

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

Serialize this value into the given Serde serializer.
