Implementations

impl FormatExpression

pub fn new( spec: Option<FormatSpec>, expression: Expression, src_ref: SrcRef, ) -> Self

Create new format expression.

Trait Implementations

impl Clone for FormatExpression

fn clone(&self) -> FormatExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatExpression

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

Formats the value using the given formatter.

impl Display for FormatExpression

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

Formats the value using the given formatter.

impl Eval for FormatExpression

fn eval(&self, context: &mut EvalContext) -> EvalResult<Value>

Evaluate a syntax element into a type T.

impl Parse for FormatExpression

fn parse(pair: Pair<'_>) -> ParseResult<Self>

impl PartialEq for FormatExpression

fn eq(&self, other: &FormatExpression) -> 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 SrcReferrer for FormatExpression

fn src_ref(&self) -> SrcRef

Return source code reference.

fn source_hash(&self) -> u64

Return source code hash.

impl TreeDisplay for FormatExpression

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

Write item into f and use {:depth$} syntax in front of your single line output to get proper indention.

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

Display as tree starting at depth 0.

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

Display as tree starting at given depth in debug mode

fn write_tree(&self, f: &mut impl Write) -> Result<()>

Display as tree starting at depth 0 into a file
