Struct MetaList

pub struct MetaList {
    pub path: Path,
    pub delimiter: MacroDelimiter,
    pub tokens: TokenStream,
}

Available on crate features full or derive only.

A structured list within an attribute, like derive(Copy, Clone).

Fields

Implementations

impl MetaList

pub fn parse_args<T: Parse>(&self) -> Result<T>

See Attribute::parse_args.

pub fn parse_args_with<F: Parser>(&self, parser: F) -> Result<F::Output>

Available on crate feature parsing only.

See Attribute::parse_args_with.

pub fn parse_nested_meta( &self, logic: impl FnMut(ParseNestedMeta<'_>) -> Result<()>, ) -> Result<()>

Available on crate feature parsing only.

See Attribute::parse_nested_meta.

Trait Implementations

impl Clone for MetaList

Available on crate feature clone-impls only.

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetaList

Available on crate feature extra-traits only.

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

Formats the value using the given formatter.

impl From<MetaList> for Meta

fn from(meta: MetaList) -> Meta

Converts to this type from the input type.

impl Hash for MetaList

Available on crate feature extra-traits only.

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 Parse for MetaList

Available on crate feature parsing only.

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for MetaList

Available on crate feature extra-traits only.

fn eq(&self, other: &Self) -> 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 ToTokens for MetaList

Available on crate feature printing only.

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.

impl Eq for MetaList

Available on crate feature extra-traits only.
