Trait Implementations

impl Clone for TryPropagationExpression

fn clone(&self) -> TryPropagationExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TryPropagationExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TryPropagationExpression

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Format<WhitespaceConfig, ()> for TryPropagationExpression

fn format( &mut self, ctx: &mut Context<'_>, prefix_ws: WhitespaceConfig, args: (), ) -> FormatOutput

Formats this type.

impl Formattable for TryPropagationExpression

fn with_prefix_ws<WITH_PREFIX_WS_O>( &mut self, ctx: &mut Context<'_>, f: &mut impl FnMut(&mut Whitespace, &mut Context<'_>) -> WITH_PREFIX_WS_O, ) -> Result<WITH_PREFIX_WS_O, ControlFlow<()>>

Accesses the prefix whitespace of this type.

fn with_strings<WITH_STRINGS_O>( &mut self, ctx: &mut Context<'_>, exclude_prefix_ws: bool, f: &mut impl FnMut(&mut AstStr, &mut Context<'_>) -> ControlFlow<WITH_STRINGS_O>, ) -> ControlFlow<WITH_STRINGS_O, bool>

Iterates over all strings in this type.

fn format_output(&mut self, ctx: &mut Context<'_>) -> FormatOutput

Returns the formatting output for this type, without formatting it.

fn prefix_ws_is_pure(&mut self, ctx: &mut Context<'_>) -> Option<bool>

Returns if the prefix whitespace is pure.

fn prefix_ws_join_prefix( &mut self, ctx: &mut Context<'_>, ws: Whitespace, ) -> Result<(), Whitespace>

Joins a string as a prefix onto the prefix whitespace of this type.

impl From<TryPropagationExpression> for OperatorExpression

fn from(value: TryPropagationExpression) -> Self

Converts to this type from the input type.

impl IntoRecursiveRoot<ExpressionInner> for TryPropagationExpression

fn into_recursive_root(self, parser: &mut Parser) -> ExpressionInner

impl ParsableRecursive<ExpressionInner> for TryPropagationExpression

type Base = !

Base type

type Prefix = !

The prefix for this type

type Suffix = TryPropagationExpressionSuffix

The suffix for this type

type Infix = !

The infix of this type

fn from_base(base: Self::Base, parser: &mut Parser) -> Self

Converts the base to this type

fn join_prefix( prefix: Self::Prefix, _: ExpressionInner, parser: &mut Parser, ) -> Self

Creates this type from it’s parts

fn join_suffix( lhs: ExpressionInner, suffix: Self::Suffix, parser: &mut Parser, ) -> Self

Creates this type from it’s parts

fn join_infix( _: ExpressionInner, infix: Self::Infix, _: ExpressionInner, parser: &mut Parser, ) -> Self

Creates this type from it’s parts

impl PartialEq for TryPropagationExpression

fn eq(&self, other: &TryPropagationExpression) -> 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 Print for TryPropagationExpression

fn print(&self, f: &mut PrintFmt)

Prints this type onto a writer

fn print_non_ws(&self, f: &mut PrintFmt)

Prints this type onto a writer excluding whitespace

fn print_to(&self, p: impl FnOnce(&Self, &mut PrintFmt)) -> PrintOutput

Prints this type using p as the printer function and returns the output

impl Serialize for TryPropagationExpression

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<OperatorExpression> for TryPropagationExpression

type Error = TryIntoError<OperatorExpression>

The type returned in the event of a conversion error.

fn try_from( value: OperatorExpression, ) -> Result<Self, TryIntoError<OperatorExpression>>

Performs the conversion.

impl TryFromRecursiveRoot<ExpressionInner> for TryPropagationExpression

fn try_from_recursive_root( root: ExpressionInner, parser: &mut Parser, ) -> Option<Self>

impl Eq for TryPropagationExpression

impl StructuralPartialEq for TryPropagationExpression
