Struct Prefix 

pub struct Prefix(/* private fields */);

Strongly-typed KERI identifier prefix (e.g., "ETest123...", "DKey456...").

A prefix is the autonomous identifier (AID) for a KERI identity. For self-addressing AIDs it starts with E (Blake3-256 digest of the inception event); for key-based AIDs it starts with D (Ed25519 public key) or another CESR derivation code.

Args:

• Inner String must start with a valid CESR derivation code (uppercase letter or digit). Enforced by new(), not by serde.

Usage:

let prefix = Prefix::new("ETest123abc".to_string())?;
assert_eq!(prefix.as_str(), "ETest123abc");

Implementations

impl Prefix

pub fn new(s: String) -> Result<Prefix, KeriTypeError>

Validates and wraps a KERI prefix string.

Accepts any valid CESR derivation code (D for Ed25519, E for Blake3, 1 for secp256k1, etc.). See [validate_prefix_derivation_code] for details.

pub fn new_unchecked(s: String) -> Prefix

Wraps a prefix string without validation (for trusted internal paths).

pub fn as_str(&self) -> &str

Returns the inner string slice.

pub fn into_inner(self) -> String

Consumes self and returns the inner String.

pub fn is_empty(&self) -> bool

Returns true if the inner string is empty (placeholder during event construction).

Trait Implementations

impl AsRef<str> for Prefix

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<str> for Prefix

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl Clone for Prefix

fn clone(&self) -> Prefix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Prefix

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

Formats the value using the given formatter.

impl Default for Prefix

fn default() -> Prefix

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Prefix

fn deserialize<D>( deserializer: D, ) -> Result<Prefix, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Prefix

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

Formats the value using the given formatter.

impl Eq for Prefix

impl Hash for Prefix

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

where __H: Hasher,

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 Prefix

fn eq(&self, other: &Prefix) -> 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 PartialEq<&str> for Prefix

fn eq(&self, other: &&str) -> 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 PartialEq<Prefix> for str

fn eq(&self, other: &Prefix) -> 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 PartialEq<Prefix> for &str

fn eq(&self, other: &Prefix) -> 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 PartialEq<str> for Prefix

fn eq(&self, other: &str) -> 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 Prefix

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
