Struct Parameter

pub struct Parameter {
    pub name: Token,
    pub colon: Option<Token>,
    pub type: Option<Pointer<TypeValue>>,
}

Parameter that a function can have. The difference between this and Name is the fact that Parameter.name can match variadic values (...) while Name can’t.

Fields

name: Token

The actual name.

colon: Option<Token>

: character.

type: Option<Pointer<TypeValue>>

The type that was with this name, defined with the : type syntax.

Trait Implementations

impl Clone for Parameter

fn clone(&self) -> Parameter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Parameter

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

Formats the value using the given formatter.

impl GetRange for Parameter

fn get_range(&self) -> Result<Range, GetRangeError>

Get the range of the node. This will only fail if Cst.status is AstStatus::HasErrors.

impl Hash for Parameter

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 Ord for Parameter

fn cmp(&self, other: &Parameter) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl Parse for Parameter

fn parse( name: Token, lexer: &mut Lexer<'_>, errors: &mut Vec<ParseError>, ) -> Option<Self>

Try parsing the current item, starting from the passed token.

impl PartialEq for Parameter

fn eq(&self, other: &Parameter) -> 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 PartialOrd for Parameter

fn partial_cmp(&self, other: &Parameter) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Print for Parameter

fn print(&self) -> String

Prints the whole token including all surrounding spaces.

impl Eq for Parameter
