Struct KeyPrefix

pub struct KeyPrefix { /* private fields */ }

A string which should be prefixed to an identifier to generate a database key.

Example

use redis_work_queue::KeyPrefix;

let cv_key = KeyPrefix::from("cv:");
// ...
let cv_id = "abcdef-123456";
assert_eq!(cv_key.of(cv_id), "cv:abcdef-123456");
// let cv_info = db.get(cv_key.of(cv_id));

Implementations

impl KeyPrefix

pub fn new(prefix: String) -> KeyPrefix

pub fn of(&self, name: &str) -> String

Returns the result of prefixing self onto name.

pub fn and(&self, other: &str) -> KeyPrefix

Returns the result of prefixing self onto other as a new KeyPrefix.

This is like KeyPrefix::concat except it only borrows self.

pub fn concat(self, other: &str) -> KeyPrefix

Returns the result of prefixing self onto other as a new KeyPrefix.

This is like KeyPrefix::and except it moves self.

Trait Implementations

impl AsRef<str> for KeyPrefix

fn as_ref(&self) -> &str

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

impl Clone for KeyPrefix

fn clone(&self) -> KeyPrefix

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyPrefix

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

Formats the value using the given formatter.

impl From<&str> for KeyPrefix

fn from(prefix: &str) -> KeyPrefix

Converts to this type from the input type.

impl From<KeyPrefix> for String

fn from(key_prefix: KeyPrefix) -> String

Converts to this type from the input type.

impl From<String> for KeyPrefix

fn from(prefix: String) -> KeyPrefix

Converts to this type from the input type.

impl PartialEq for KeyPrefix

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