Struct erg_compiler::hir::DefaultParamSignature

pub struct DefaultParamSignature {
    pub sig: NonDefaultParamSignature,
    pub default_val: Expr,
}

Once the default_value is set to Some, all subsequent values must be Some

Fields

sig: NonDefaultParamSignature

default_val: Expr

Implementations

impl DefaultParamSignature

pub const fn new(sig: NonDefaultParamSignature, default_val: Expr) -> Self

pub const fn inspect(&self) -> Option<&Str>

pub const fn name(&self) -> Option<&VarName>

Trait Implementations

impl Clone for DefaultParamSignature

fn clone(&self) -> DefaultParamSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DefaultParamSignature

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

Formats the value using the given formatter.

impl Display for DefaultParamSignature

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

Formats the value using the given formatter.

impl Hash for DefaultParamSignature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Locational for DefaultParamSignature

fn loc(&self) -> Location

NOTE: loc cannot be treated as a light method when self is a large grammatical element. If possible, delay the computation by passing &impl Locational or other means.

fn ln_begin(&self) -> Option<u32>

1-origin

fn ln_end(&self) -> Option<u32>

fn col_begin(&self) -> Option<u32>

0-origin

fn col_end(&self) -> Option<u32>

impl NestedDisplay for DefaultParamSignature

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

impl NoTypeDisplay for DefaultParamSignature

fn to_string_notype(&self) -> String

impl PartialEq for DefaultParamSignature

fn eq(&self, other: &DefaultParamSignature) -> 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.
