Struct ResourcePattern 

pub struct ResourcePattern { /* private fields */ }

A pattern that matches resources.

Supports exact matches and glob patterns (*, **, ?).

Implementations

impl ResourcePattern

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

Create a new resource pattern.

Errors

Returns CapabilityError::InvalidPattern if the glob pattern is invalid or contains path traversal sequences (..).

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

Create an exact match pattern.

Errors

Returns CapabilityError::InvalidPattern if the pattern contains path traversal sequences (..).

pub fn file_dir(path: impl Into<String>) -> CapabilityResult<Self>

Create a pattern matching a file directory and all contents beneath it.

Example: file_dir("/home/user") matches file:///home/user/any/nested/file.

Errors

Returns CapabilityError::InvalidPattern if the path contains path traversal.

pub fn file_exact(path: impl Into<String>) -> CapabilityResult<Self>

Create a pattern matching an exact file path.

Example: file_exact("/home/user/file.txt") matches only file:///home/user/file.txt.

Errors

Returns CapabilityError::InvalidPattern if the path contains path traversal.

pub fn mcp_tool( server: impl Into<String>, tool: impl Into<String>, ) -> CapabilityResult<Self>

Create a pattern matching a specific MCP tool on a specific server.

Example: mcp_tool("filesystem", "read_file") matches mcp://filesystem:read_file.

Errors

Returns CapabilityError::InvalidPattern if server or tool names contain path traversal sequences.

pub fn mcp_server(server: impl Into<String>) -> CapabilityResult<Self>

Create a pattern matching all tools on an MCP server.

Example: mcp_server("filesystem") matches mcp://filesystem:read_file, mcp://filesystem:write_file, etc.

Errors

Returns CapabilityError::InvalidPattern if the glob compilation fails.

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

Check if this pattern matches a resource.

Resources containing path traversal sequences (..) are always rejected.

pub fn as_str(&self) -> &str

Get the pattern string.

pub fn is_glob(&self) -> bool

Check if this is a glob pattern.

Trait Implementations

impl Clone for ResourcePattern

fn clone(&self) -> ResourcePattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResourcePattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ResourcePattern

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ResourcePattern

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

Formats the value using the given formatter.

impl Hash for ResourcePattern

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ResourcePattern

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 ResourcePattern

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

where S: Serializer,

Serialize this value into the given Serde serializer.
