Struct Argument 

pub struct Argument {
    pub id: Option<Identifier>,
    pub expression: Expression,
    pub src_ref: SrcRef,
}

Argument in a Call.

Fields

id: Option<Identifier>

Name of the argument

expression: Expression

Value of the argument

src_ref: SrcRef

Source code reference

Implementations

impl Argument

pub fn derived_name(&self) -> Option<Identifier>

Returns the name, if self.name is some. If self.name is None, try to extract the name from the expression

Trait Implementations

impl Clone for Argument

fn clone(&self) -> Argument

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Argument

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

Formats the value using the given formatter.

impl Display for Argument

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

Formats the value using the given formatter.

impl Eval<ArgumentValue> for Argument

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

Evaluate Argument and return ArgumentValue

impl OrdMapValue<Identifier> for Argument

fn key(&self) -> Option<Identifier>

return some unique key of this value or None

impl Parse for Argument

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

impl PartialEq for Argument

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

fn src_ref(&self) -> SrcRef

Return source code reference.

fn source_hash(&self) -> u64

Return source code hash.

impl TreeDisplay for Argument

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
