Struct ArnMatcher 

pub struct ArnMatcher { /* private fields */ }

Advanced ARN matching capabilities for policy evaluation

Implementations

impl ArnMatcher

pub fn new<I>(patterns: I) -> Result<Self, ArnError>

where I: IntoIterator<Item = String>,

Create a new ARN matcher with a set of patterns

Errors

Returns ArnError if any of the provided patterns cannot be parsed as valid ARNs.

pub fn from_pattern(pattern: &str) -> Result<Self, ArnError>

Create a matcher from a single pattern

Errors

Returns ArnError if the pattern cannot be parsed as a valid ARN.

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

Check if any pattern matches the given ARN

Errors

Returns ArnError if the ARN cannot be parsed or if pattern matching fails.

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

Check if any pattern matches the given parsed ARN

pub fn matching_patterns(&self, arn: &str) -> Result<Vec<&str>, ArnError>

Get all patterns that match the given ARN

Errors

Returns ArnError if the ARN cannot be parsed.

pub fn filter_matching<'a>( &self, arns: &'a [Arn], ) -> Result<Vec<&'a Arn>, ArnError>

Find ARNs from a collection that match any of our patterns

Errors

Returns ArnError if any ARN in the collection cannot be parsed.

pub fn matches_all(&self) -> bool

Check if this matcher would match everything (contains “*”)

pub fn patterns(&self) -> Vec<&str>

Get the list of patterns this matcher uses

pub fn combine(matchers: Vec<ArnMatcher>) -> Self

Create a matcher that combines multiple matchers (OR logic)
