Backend features

Fields

persistent: bool

Whether the database supports persistent storage.

event_expiration: bool

Whether the database supports event expiration (NIP-40)

When supported, the database will automatically exclude expired events from query results and/or delete them.

full_text_search: bool

Whether the database supports full-text search (NIP-50)

request_to_vanish: bool

Whether the database supports the request to vanish (NIP-62)

impl PartialEq for Features

fn eq(&self, other: &Features) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Features

fn partial_cmp(&self, other: &Features) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool
