Enum GenericParameterInfoDefault

pub enum GenericParameterInfoDefault {
    ERROR,
    Name(Token),
    Pack(Pointer<TypeValue>),
}

Struct holding default values for generic arguments.

Variants

ERROR

There was an error parsing.

Name(Token)

A simple name.

type Foo<T = string> = "Foo"

Pack(Pointer<TypeValue>)

A generic pack.

type Foo<T... = string...> = "Foo"
type Bar<T... = ...string> = "Bar"
type Qux<T... = (string, number)> = "Qux"

Trait Implementations

impl Clone for GenericParameterInfoDefault

fn clone(&self) -> GenericParameterInfoDefault

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenericParameterInfoDefault

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

Formats the value using the given formatter.

impl Default for GenericParameterInfoDefault

fn default() -> GenericParameterInfoDefault

Returns the “default value” for a type.

impl GetRange for GenericParameterInfoDefault

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

Get the range of the node.

impl Hash for GenericParameterInfoDefault

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 GenericParameterInfoDefault

fn cmp(&self, other: &GenericParameterInfoDefault) -> 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 GenericParameterInfoDefault

fn parse( token: Token, lexer: &mut Lexer, errors: &mut Vec<Error>, ) -> Option<Self>

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

impl PartialEq for GenericParameterInfoDefault

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

fn partial_cmp(&self, other: &GenericParameterInfoDefault) -> 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 GenericParameterInfoDefault

fn print_final_trivia(&self) -> String

Prints only the very final trivia. Used for the default implementation of Print::print, which just joins Print::print_without_final_trivia and this function.

fn print_without_final_trivia(&self) -> String

Prints the whole token including all surrounding trivia, excluding the very last trailing trivia.

fn print(&self) -> String

Prints the whole token including all surrounding trivia.

impl TryParse for GenericParameterInfoDefault

fn try_parse(lexer: &mut Lexer, errors: &mut Vec<Error>) -> Option<O>

Try parsing and reset the lexer’s state upon failure.

impl Eq for GenericParameterInfoDefault
