Trait Implementations

impl FromMeta for Meta

fn from_meta(value: &Meta) -> Result<Self>

Create an instance from a syn::Meta by dispatching to the format-appropriate trait function. This generally should not be overridden by implementers.

fn from_nested_meta(item: &NestedMeta) -> Result<Self>

fn from_empty() -> Result<Self>

Create an instance from the presence of the word in the attribute with no additional options specified.

fn from_list(items: &[&NestedMeta]) -> Result<Self>

Create an instance from a list of nested meta items.

fn from_value(value: &MetaValue) -> Result<Self>

Create an instance from a literal value of either foo = "bar" or foo("bar"). This dispatches to the appropriate method based on the type of literal encountered, and generally should not be overridden by implementers.

fn from_lit(lit: &Lit) -> Result<Self>

fn from_char<S: Spanned>(value: char, span: &S) -> Result<Self>

Create an instance from a char literal in a value position.

fn from_int<S: Spanned>(value: u64, span: &S) -> Result<Self>

Create an instance from a int literal in a value position.

fn from_path(value: &Path) -> Result<Self>

Create an instance from a char literal in a value position.

fn from_string<S: Spanned>(value: &str, span: &S) -> Result<Self>

Create an instance from a string literal in a value position.

fn from_bool<S: Spanned>(value: bool, span: &S) -> Result<Self>

Create an instance from a bool literal in a value position.

fn from_ident(value: &Ident) -> Result<Self>

impl Clone for Meta

fn clone(&self) -> Meta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<Meta> for Meta

fn eq(&self, other: &Meta) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Meta) -> bool

This method tests for !=.

impl Debug for Meta

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl ToTokens for Meta

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

Convert self directly into a TokenStream object.

impl Parse for Meta

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