Trait Implementations

impl Borrow<str> for IdentString

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl Debug for IdentString

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

Formats the value using the given formatter.

impl Default for IdentString

fn default() -> IdentString

Returns the “default value” for a type.

impl From<Ident> for IdentString

fn from(ident: Ident) -> Self

Converts to this type from the input type.

impl FromMacro for IdentString

fn from_one(tt: TokenTree) -> Result<Self, Error>

This will be called if there is only one item

const PREFER_MANY: bool = false

Hint to All and similar extractors to disable length validation.

fn from_many(tokens: TokenStream) -> Result<Self, Error>

This will be called if there is more than one item.

fn peek(tt: &TokenTree) -> bool

Look ahead and determine parsability.

impl Hash for IdentString

fn hash<__H: Hasher>(&self, state: &mut __H)

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 PartialEq for IdentString

fn eq(&self, other: &IdentString) -> 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 IdentString

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.
