Struct ParamAttrs

pub struct ParamAttrs {
    pub positional: bool,
    pub named: bool,
    pub variadic: bool,
    pub settable: bool,
}

Describes a function parameter.

Fields

positional: bool

Is the parameter positional?

named: bool

Is the parameter named?

Can be true even if positional is true if the parameter can be given in both variants.

variadic: bool

Can the parameter be given any number of times?

settable: bool

Is the parameter settable with a set rule?

Implementations

impl ParamAttrs

pub fn positional() -> ParamAttrs

pub fn named() -> ParamAttrs

pub fn variadic() -> ParamAttrs

Trait Implementations

impl Clone for ParamAttrs

fn clone(&self) -> ParamAttrs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParamAttrs

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

Formats the value using the given formatter.

impl Default for ParamAttrs

fn default() -> ParamAttrs

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ParamAttrs

fn deserialize<__D>( __deserializer: __D, ) -> Result<ParamAttrs, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&ParamInfo> for ParamAttrs

fn from(param: &ParamInfo) -> ParamAttrs

Converts to this type from the input type.

impl Hash for ParamAttrs

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

where __H: Hasher,

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 ParamAttrs

fn cmp(&self, other: &ParamAttrs) -> 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 PartialEq for ParamAttrs

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

fn partial_cmp(&self, other: &ParamAttrs) -> 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 Serialize for ParamAttrs

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
