Struct Query 

pub struct Query {
    pub kinds: Vec<u16>,
    pub z_tags: Vec<String>,
    pub d_tags: Vec<String>,
    pub authors: Vec<String>,
    pub since: Option<u64>,
    pub until: Option<u64>,
    pub limit: Option<usize>,
}

The slice of a relay query the Community protocol needs: event kinds, the z pseudonym tag values, and an optional since floor. Production translates this into a Nostr Filter; the in-memory relay matches it directly.

Fields

kinds: Vec<u16>

z_tags: Vec<String>

z tag values to match (OR). Empty = match any (no z constraint).

d_tags: Vec<String>

d tag (identifier) values to match (OR). Empty = no d constraint. Used to locate addressable events (e.g. a public-invite bundle by its token locator).

authors: Vec<String>

Author pubkeys (hex) to match (OR). Empty = any author.

since: Option<u64>

Lower bound on created_at (seconds), inclusive.

until: Option<u64>

Upper bound on created_at (seconds), inclusive — pages OLDER history (events strictly/inclusively before a scroll cursor).

limit: Option<usize>

Max events to return (newest-first), the relay-side page cap. None = no limit.

Implementations

impl Query

pub fn matches(&self, event: &Event) -> bool

Does event satisfy this query?

pub fn to_filter(&self) -> Filter

Translate to a Nostr relay Filter for the live client.

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl Default for Query

fn default() -> Query

Returns the “default value” for a type.
