Struct LoopFingerprint 

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

A Loop fingerprint (one-way hash of card_id)

Format: loop_fp_{64 hex characters}

This type ensures fingerprints are always properly formatted and cannot be confused with raw card IDs.

Implementations

impl LoopFingerprint

pub fn as_str(&self) -> &str

Get the fingerprint string

pub fn into_string(self) -> String

Convert to owned string

pub fn is_valid_format(s: &str) -> bool

Check if a string is a valid Loop fingerprint format

pub fn parse(s: &str) -> Option<Self>

Parse from string (validates format)

Trait Implementations

impl AsRef<str> for LoopFingerprint

fn as_ref(&self) -> &str

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

impl Clone for LoopFingerprint

fn clone(&self) -> LoopFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoopFingerprint

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

Formats the value using the given formatter.

impl Display for LoopFingerprint

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

Formats the value using the given formatter.

impl Hash for LoopFingerprint

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 LoopFingerprint

fn eq(&self, other: &LoopFingerprint) -> 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.
