Pattern

Enum Pattern 

Source
pub enum Pattern {
    Text(String),
    Regex {
        regex: String,
        flags: String,
    },
}
Expand description

String-or-regex pattern. Wire-compatible: plain JSON string ↔ Pattern::Text; tagged object {regex, flags}Pattern::Regex.

Case-insensitive 模式跟 TS v1.5 c5i-d 1:1: regex 缺 /i flag 自动注入; text 走 eq_ignore_ascii_case 模拟 toLowerCase strict equal.

Variants§

§

Text(String)

Plain literal string. Empty string never matches anything (TS resolve-selector.ts:178 if (pattern === '') return false).

§

Regex

Compiled-on-call regex. flags defaults to “i” when absent to satisfy v1.5 c5i-d maestro parity.

Fields

§regex: String

Regex source string (PCRE-like syntax via the regex crate).

§flags: String

Flags string (currently only "i" is honored; defaulted to "i").

Implementations§

Source§

impl Pattern

Source

pub fn text<S: Into<String>>(s: S) -> Self

Construct a plain text pattern.

Source

pub fn regex<P: Into<String>>(pattern: P) -> Self

Construct a regex pattern. Auto-injects i flag if absent.

Source

pub fn regex_with_flags<P: Into<String>, F: Into<String>>( pattern: P, flags: F, ) -> Self

Construct a regex pattern with explicit flags.

Source

pub fn compile(&self) -> Result<CompiledPattern, Error>

Compile the wire-form pattern into a hot-path-ready CompiledPattern. One-time cost (~5-50 μs for regex compile, ~ns for text); the resulting CompiledPattern matches in 5-50 ns per call — the regex compile gets fully amortized after just one re-use.

Use match_text for one-shot SDK convenience; use match_text_compiled inside any hot resolver loop after Pattern::compile() once.

Returns Err(regex::Error) only for malformed regex patterns; text patterns are infallible.
