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

path: Path

delimiter: MacroDelimiter

tokens: TokenStream

Implementations

impl MetaList

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

Available on crate feature parsing only.

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 copy 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
