Struct cedar_policy_core::ast::Pattern

pub struct Pattern { /* private fields */ }

Represent a pattern literal (the RHS of the like operator) Also provides an implementation of the Display trait as well as a wildcard matching method.

Implementations

impl Pattern

pub fn new(elems: impl IntoIterator<Item = PatternElem>) -> Self

Explicitly create a pattern literal out of a vector of pattern elements

pub fn get_elems(&self) -> &[PatternElem]

Getter to the wrapped vector

pub fn iter(&self) -> impl Iterator<Item = &PatternElem>

Iterate over pattern elements

impl Pattern

pub fn wildcard_match(&self, text: &str) -> bool

Find if the argument text matches the pattern

Trait Implementations

impl Clone for Pattern

fn clone(&self) -> Pattern

Returns a copy 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<'de> Deserialize<'de> for Pattern

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Pattern

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

Formats the value using the given formatter.

impl Hash for Pattern

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 Pattern

fn eq(&self, other: &Pattern) -> 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 Pattern

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Pattern
