Struct CompiledPattern 

pub struct CompiledPattern { /* private fields */ }

A regex pattern compiled once at construction or deserialisation time.

Stores both the compiled Regex and the source string so that the rule remains Clone / PartialEq / Serialize without needing to recompile on every match. Compilation errors surface at the construction site (e.g. schema load) rather than per-request on the validation hot path.

Implementations

impl CompiledPattern

pub fn new(pattern: impl Into<String>) -> Result<Self, Error>

Compile a regex pattern.

Errors

Returns the underlying regex::Error if pattern is not a valid regular expression.

pub const fn regex(&self) -> &Regex

Borrow the compiled regex for matching.

pub fn as_str(&self) -> &str

Borrow the original pattern source.

pub fn is_match(&self, value: &str) -> bool

Test whether the input string matches this pattern.

Trait Implementations

impl Clone for CompiledPattern

fn clone(&self) -> CompiledPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompiledPattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CompiledPattern

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for CompiledPattern

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

Formats the value using the given formatter.

impl PartialEq for CompiledPattern

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 CompiledPattern

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

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for CompiledPattern

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for CompiledPattern

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
