Struct scratchstack_arn::ArnPattern

pub struct ArnPattern { /* private fields */ }

An Amazon Resource Name (ARN) statement in an IAM Aspen policy.

This is used to match Arn objects from a resource statement in the IAM Aspen policy language. For example, an ArnPattern created from arn:aws*:ec2:us-*-?:123456789012:instance/i-* would match the following Arn objects:

• arn:aws:ec2:us-east-1:123456789012:instance/i-1234567890abcdef0
• arn:aws-us-gov:ec2:us-west-2:123456789012:instance/i-1234567890abcdef0

Patterns are similar to glob statements with a few differences:

• The * character matches any number of characters, including none, within a single segment of the ARN.
• The ? character matches any single character within a single segment of the ARN.

ArnPattern objects are immutable.

Implementations

impl ArnPattern

pub fn new(
    partition: &str,
    service: &str,
    region: &str,
    account_id: &str,
    resource: &str
) -> Self

Create a new ARN pattern from the specified components.

• partition - The partition the resource is in.
• service - The service the resource belongs to.
• region - The region the resource is in.
• account_id - The account ID the resource belongs to.
• resource - The resource name.

pub fn partition(&self) -> &GlobPattern

Retreive the pattern for the partition.

pub fn service(&self) -> &GlobPattern

Retrieve the pattern for the service.

pub fn region(&self) -> &GlobPattern

Retrieve the pattern for the region.

pub fn account_id(&self) -> &GlobPattern

Retrieve the pattern for the account ID.

pub fn resource(&self) -> &GlobPattern

Retrieve the pattern for the resource.

pub fn matches(&self, arn: &Arn) -> bool

Indicate whether the specified Arn matches this pattern.

Trait Implementations

impl Clone for ArnPattern

fn clone(&self) -> ArnPattern

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArnPattern

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

Formats the value using the given formatter.

impl Display for ArnPattern

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

Formats the value using the given formatter.

impl FromStr for ArnPattern

fn from_str(s: &str) -> Result<Self, ArnError>

Create an ArnPattern from a string.

type Err = ArnError

The associated error which can be returned from parsing.

impl Hash for ArnPattern

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq<ArnPattern> for ArnPattern

fn eq(&self, other: &ArnPattern) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
