Struct PikeVM

pub struct PikeVM {
    pub(crate) config: Config,
    pub(crate) nfa: NFA,
    pub(crate) wasm: CompiledRegex,
}

A compiled regular expression represented as a Pike VM, ready for matching.

Fields

config: Config

nfa: NFA

wasm: CompiledRegex

Implementations

impl PikeVM

pub fn new(pattern: &str) -> Result<PikeVM, BuildError>

Compiles a single regular expression pattern into a new PikeVM using the default builder.

pub fn new_many<P: AsRef<str>>(patterns: &[P]) -> Result<PikeVM, BuildError>

Compiles multiple regular expression patterns into a single new PikeVM using the default builder.

pub fn new_from_nfa(nfa: NFA) -> Result<PikeVM, BuildError>

Creates a new PikeVM directly from a Thompson NFA using the default builder.

pub fn always_match() -> Result<PikeVM, BuildError>

Creates a PikeVM that always matches the empty string at any position.

pub fn never_match() -> Result<PikeVM, BuildError>

Creates a PikeVM that never matches.

pub fn config() -> Config

Returns a new default Config for configuring a Builder.

pub fn builder() -> Builder

Returns a new default Builder for compiling regular expressions.

pub fn pattern_len(&self) -> usize

Returns the number of patterns compiled into this PikeVM.

pub fn get_config(&self) -> &Config

Return the config for this PikeVM.

Note that this is the configuration used to build the PikeVM, not necessarily the configuration used for a specific match operation.

pub fn get_nfa(&self) -> &NFA

Returns a reference to the underlying NFA.

This is the NFA that was compiled into the PikeVM.

pub fn get_wasm(&self) -> &[u8]

Returns a reference to the compiled WASM bytes.

These bytes represent the compiled PikeVM logic.

Trait Implementations
