Enum AttrArgs 

pub enum AttrArgs {
    Parens(ParenthesisGroupContaining<Vec<TokenTree>>),
    Equals(AttrEqualsArgs),
}

Arguments for attributes - either parenthesized (args) or with equals = value

Variants

Parens(ParenthesisGroupContaining<Vec<TokenTree>>)

Parenthesized arguments like (auto_increment)

Equals(AttrEqualsArgs)

Equals-style arguments like = 'v'

Trait Implementations

impl Debug for AttrArgs

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

Formats the value using the given formatter.

impl Parser for AttrArgs

fn parser(tokens: &mut TokenIter) -> Result<AttrArgs, Error>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl ToTokens for AttrArgs

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

Write &self to the given TokenStream.

fn to_token_iter(&self) -> TokenIter

Convert &self into a TokenIter object.

fn into_token_iter(self) -> TokenIter

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
