Struct Key 

pub struct Key { /* private fields */ }

Representa uma chave hierárquica no datastore

Permite navegar por uma estrutura de diretórios com operações de pai/filho e conversões para diferentes formatos.

Implementations

impl Key

pub fn new<S: Into<String>>(path: S) -> Self

Cria uma nova chave a partir de um caminho

Exemplos

use guardian_db::data_store::Key;

let key = Key::new("/users/alice/profile");
let key = Key::new("config/database/host");

pub fn root() -> Self

Cria uma chave raiz vazia

pub fn child<S: Into<String>>(&self, name: S) -> Self

Cria uma chave filha adicionando um segmento

pub fn parent(&self) -> Option<Self>

Retorna a chave pai, se existir

pub fn is_empty(&self) -> bool

Verifica se a chave está vazia (raiz)

pub fn name(&self) -> Option<&str>

Retorna o último segmento da chave

pub fn segments(&self) -> &[String]

Retorna todos os segmentos da chave

pub fn depth(&self) -> usize

Retorna a profundidade da chave (número de segmentos)

pub fn is_descendant_of(&self, other: &Key) -> bool

Verifica se esta chave é descendente de outra

pub fn as_str(&self) -> String

Converte para string com formato de caminho

pub fn as_bytes(&self) -> Vec<u8>

Converte para bytes UTF-8

Trait Implementations

impl Clone for Key

fn clone(&self) -> Key

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Key

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

Formats the value using the given formatter.

impl Display for Key

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

Formats the value using the given formatter.

impl From<&str> for Key

fn from(path: &str) -> Self

Converts to this type from the input type.

impl From<String> for Key

fn from(path: String) -> Self

Converts to this type from the input type.

impl Hash for Key

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 Key

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