Struct Prefix 

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

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

A prefix is the self-addressing identifier derived from the inception event’s Blake3 hash. Always starts with ‘E’ (Blake3-256 derivation code).

Args:

• Inner String should start with 'E' (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<Self, KeriTypeError>

Validates and wraps a KERI prefix string.

pub fn new_unchecked(s: String) -> Self

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

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<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Prefix

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

Formats the value using the given formatter.

impl From<Prefix> for String

fn from(p: Prefix) -> String

Converts to this type from the input type.

impl Hash for Prefix

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<&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 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 Serialize for Prefix

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 Prefix
