Struct MetaList 

pub struct MetaList {
    pub span: SourceSpan,
    pub name: Ident,
    pub items: Vec<MetaExpr>,
}

Represents the metadata of a named list crate::ast::Attribute, i.e. @name(item0, .., itemN)

Fields

span: SourceSpan

name: Ident

The identifier used as the name of this attribute

items: Vec<MetaExpr>

The list of items representing the value of this attribute - will always contain at least one element when parsed.

Trait Implementations

impl Arbitrary for MetaList

Available on crate feature arbitrary only.

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = BoxedStrategy<MetaList>

The type of Strategy used to generate values of type Self.

fn arbitrary_with( _args: <MetaList as Arbitrary>::Parameters, ) -> <MetaList as Arbitrary>::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for MetaList

fn clone(&self) -> MetaList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetaList

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

Formats the value using the given formatter.

impl Deserializable for MetaList

fn read_from<R>(source: &mut R) -> Result<MetaList, DeserializationError>

where R: ByteReader,

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn min_serialized_size() -> usize

Returns the minimum serialized size for one instance of this type.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

fn read_from_bytes_with_budget( bytes: &[u8], budget: usize, ) -> Result<Self, DeserializationError>

Deserializes Self from bytes with a byte budget limit.

impl<'de> Deserialize<'de> for MetaList

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<MetaList> for Attribute

fn from(value: MetaList) -> Attribute

Converts to this type from the input type.

impl Hash for MetaList

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,

impl Ord for MetaList

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

This method returns an Ordering between self and other.

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 MetaList

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

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 Serializable for MetaList

fn write_into<W>(&self, target: &mut W)

where W: ByteWriter,

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>
