Struct Matcher

pub struct Matcher<'a, S = usize, A = DenseDFA<&'a [S], S>>
where
    S: StateID,
    A: DFA<ID = S>,
{ /* private fields */ }

A reference to a Pattern that matches a single input.

Implementations

impl<'a, S, A> Matcher<'a, S, A>

where S: StateID, A: DFA<ID = S>,

pub fn is_matched(&self) -> bool

Returns true if this Matcher has matched any input that has been provided.

pub fn matches(self, s: &impl AsRef<str>) -> bool

Returns true if this pattern matches the formatted output of the given type implementing fmt::Debug.

pub fn debug_matches(self, d: &impl Debug) -> bool

Returns true if this pattern matches the formatted output of the given type implementing fmt::Debug.

pub fn display_matches(self, d: &impl Display) -> bool

Returns true if this pattern matches the formatted output of the given type implementing fmt::Display.

pub fn read_matches(self, io: impl Read + Sized) -> Result<bool>

Returns either a bool indicating whether or not this pattern matches the data read from the provided io::Read stream, or an io::Error if an error occurred reading from the stream.

Trait Implementations

impl<'a, S, A> Clone for Matcher<'a, S, A>

where S: StateID + Clone, A: DFA<ID = S> + Clone,

fn clone(&self) -> Matcher<'a, S, A>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, S, A> Debug for Matcher<'a, S, A>

where S: StateID + Debug, A: DFA<ID = S> + Debug,

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

Formats the value using the given formatter.

impl<'a, S, A> Write for Matcher<'a, S, A>

where S: StateID, A: DFA<ID = S>,

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.

impl<'a, S, A> Write for Matcher<'a, S, A>

where S: StateID, A: DFA<ID = S>,

fn write(&mut self, bytes: &[u8]) -> Result<usize, Error>

Writes a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<(), Error>

Flushes this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

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

Attempts to write multiple buffers into this writer.

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

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adapter for this instance of Write.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
