Struct ResourcePattern 

pub struct ResourcePattern { /* private fields */ }

Represents a pattern that is used by ACLs to match zero or more Resources.

Corresponds to org.apache.kafka.common.resource.ResourcePattern.

Implementations

impl ResourcePattern

pub const WILDCARD_RESOURCE: &str = "*"

A special literal resource name that corresponds to ‘all resources of a certain type’.

pub fn new( resource_type: ResourceType, name: impl Into<String>, pattern_type: PatternType, ) -> Result<ResourcePattern, Error>

Create a pattern using the supplied parameters.

Arguments

• resource_type - specific resource type
• name - resource name, which can be the Self::WILDCARD_RESOURCE
• pattern_type - specific resource pattern type, which controls how the pattern will match resource names

Errors

Returns Error::LocalIllegalArgument if resource_type is ResourceType::Any, or pattern_type is PatternType::Match or PatternType::Any (mirrors Java’s IllegalArgumentException).

pub fn resource_type(&self) -> ResourceType

Return the specific resource type this pattern matches.

pub fn name(&self) -> &str

Return the resource name.

pub fn pattern_type(&self) -> PatternType

Return the resource pattern type.

pub fn to_filter(&self) -> ResourcePatternFilter

Return a filter which matches only this pattern.

pub fn is_unknown(&self) -> bool

Return true if this pattern has any UNKNOWN components.

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 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: &ResourcePattern) -> 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.
