Struct SerdeDFA

pub struct SerdeDFA<'data> { /* private fields */ }

A serde-compatible version of [regex_automata::dfa::sparse::DFA].

This does not implement serde::Deserialize directly, as binary deserialization is not supported in big-endian platforms. Self::maybe_deserialize can be used to deserialize to Option<SerdeDFA>.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

Implementations

impl<'data> SerdeDFA<'data>

pub fn maybe_deserialize<'de: 'data, D>( deserializer: D, ) -> Result<Option<Self>, D::Error>

where D: Deserializer<'de>,

Deserializes to Option<Self>. Will return None for non-human-readable serialization formats on big-endian systems, as regex_automata serialization is endian-sensitive.

impl<'data> SerdeDFA<'data>

pub const unsafe fn from_dfa_bytes_unchecked(dfa_bytes: &'data [u8]) -> Self

Creates a SerdeDFA from raw bytes. Used internally by databake.

Safety

dfa_bytes has to be a valid DFA (regex_automata::dfa::sparse::DFA::from_bytes(dfa_bytes).is_ok())

pub fn new(pattern: Cow<'data, str>) -> Result<Self, DataError>

Creates a SerdeDFA from a regex.

pub fn deref(&'data self) -> DFA<&'data [u8]>

Returns the represented [DFA]

Trait Implementations

impl Bake for SerdeDFA<'_>

fn bake(&self, env: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl BakeSize for SerdeDFA<'_>

fn borrows_size(&self) -> usize

Returns the size

impl<'data> Clone for SerdeDFA<'data>

fn clone(&self) -> SerdeDFA<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for SerdeDFA<'data>

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

Formats the value using the given formatter.

impl PartialEq for SerdeDFA<'_>

fn eq(&self, other: &Self) -> 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 Serialize for SerdeDFA<'_>

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> Yokeable<'a> for SerdeDFA<'static>

type Output = SerdeDFA<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

impl<'zf, 'zf_inner> ZeroFrom<'zf, SerdeDFA<'zf_inner>> for SerdeDFA<'zf>

fn zero_from(this: &'zf SerdeDFA<'zf_inner>) -> Self

Clone the other C into a struct that may retain references into C.
