impl Parse for nyas

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

impl PartialEq for nyas

fn eq(&self, _other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> CloneToUninit for T
where T: Clone,

unsafe fn clone_to_uninit(&self, dest: *mut u8)

🔬This is a nightly-only experimental API. (clone_to_uninit)

Performs copy-assignment from self to dest. Read more

impl<T> EasyArgument for T
where T: EasyToken,

fn name_display() -> &'static str

Returns attribute name for display purposes.

fn name_span(&self) -> Span

Returns attribute name for display purposes.

impl<T> EasyArgumentField for T
where T: EasyArgumentGroup,

fn try_parse( lookahead1: &Lookahead1<'_>, stream: &ParseBuffer<'_>, ) -> Result<Option<T>, Error>

Attempt to parse attribute field. Returns some field when parsing succeeds. Returns none if attribute peeking returns false, signalling that stream contains some other attribute. Returns error if peeking returns true but parsing fails.

fn try_extend( &mut self, lookahead1: &Lookahead1<'_>, stream: &ParseBuffer<'_>, ) -> Result<bool, Error>

Attempt to parse attribute field when it already has been successfully parsed. Field value should extend itself with newly parsed attribute or return error. Returns true when parsing and extending succeeds. Returns false if attribute peeking returns false, signalling that stream contains some other attribute. Returns error if peeking returns true but parsing or extending fails.

fn missing() -> Result<T, String>

Called if the attribute field was never parsed. Returns error if attribute is mandatory. Otherwise returns an instance that will be used to build attributes structure.

impl<T> EasyArgumentGroup for T
where T: EasyArgument,

fn try_parse( lookahead1: &Lookahead1<'_>, stream: &ParseBuffer<'_>, ) -> Result<Option<T>, Error>

Attempt to parse attribute group. Returns some attribute when parsing succeeds. Returns none if attribute peeking returns false, signalling that stream contains some other attribute. Returns error if peeking returns true but parsing fails.

fn overlap_error(&self, other: &T) -> Error

Produces error with appropriate message when the attribute group overlaps another instance. This is called by certain EasyArgumentField implementations. Read more

fn missing_error() -> String

Produces error with appropriate message when the attribute group is missing. This is called by certain EasyArgumentField implementations.

impl<T> EasyPeek for T
where T: Token + Parse,

fn peek(lookahead1: &Lookahead1<'_>) -> bool

Peek head token before parsing.

fn peek_stream(stream: &ParseBuffer<'_>) -> bool

Peek head token before parsing.

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T> Spanned for T
where T: Spanned + ?Sized,
