Implementations

impl Target

fn perform_check(self, ts: TokenStream) -> Option<Error>

Checks if ts can parse as self, returning the error if not

fn include_syntax(self, file: &str) -> TokenStream

Tokens for include!... to include syntax element(s) like self

fn combine_outputs( self, err: TokenStream, expansion: TokenStream, ) -> TokenStream

Make a single output, syntactically a self.target, out of pieces

err is a compile_error! call, and expansion is typically the template expansion output.

Trait Implementations

impl Clone for Target

fn clone(&self) -> Target

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DdOptValDescribable for Target

const DESCRIPTION: &'static str = "expected output syntax (`expect` option)"

impl Debug for Target

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

Formats the value using the given formatter.

impl Display for Target

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

Formats the value using the given formatter.

impl FromStr for Target

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Target, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for Target

fn eq(&self, other: &Target) -> 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 TryFrom<&str> for Target

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Target, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl Copy for Target

impl Eq for Target

impl StructuralPartialEq for Target
