Struct Pattern 

pub struct Pattern { /* private fields */ }

An entity-name pattern. Holds the original pattern string (for serialization round-tripping and operator-facing diagnostics) plus a WildMatch matcher pre-compiled at deserialize time so route resolution doesn’t re-parse the pattern on every request. Custom Serialize / Deserialize make this transparent to YAML — it serializes as a plain string, just like the previous String field did.

Glob syntax (via wildmatch):

• * matches any sequence of characters (including empty).
• ? matches any single character.

The previous hand-rolled matcher only handled trailing-* correctly: *suffix patterns silently matched almost nothing, and multi-star patterns like ** accidentally matched everything. Both shapes are real security footguns for scope/tool restriction rules — switching to wildmatch gives us full single-segment glob semantics.

Implementations

impl Pattern

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

Compile a pattern. Done once at config load; subsequent matches() calls reuse the compiled WildMatch.

pub fn matches(&self, name: &str) -> bool

Match the given name against the compiled pattern.

pub fn as_str(&self) -> &str

The original pattern string (e.g., "hr-*").

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pattern

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

Formats the value using the given formatter.

impl Default for Pattern

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Pattern

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

Deserialize this value from the given Serde deserializer.

impl Serialize for Pattern

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

Serialize this value into the given Serde serializer.
