Struct DbEventFilter 

pub struct DbEventFilter {
    pub limit: Option<i32>,
    pub not_senders: Option<Vec<String>>,
    pub not_types: Option<Vec<String>>,
    pub senders: Option<Vec<String>>,
    pub types: Option<Vec<String>>,
}

General Event filters.

Fields

limit: Option<i32>

The Limit of events returned. It should always be more than 0 and and have a reasonable maximum.

NOTE: this field should never return None, but since the type checking by sqlx does not allow for overwrite or constraint on the types, we will handle it at the application level.

not_senders: Option<Vec<String>>

Events from these senders should be excluded.

not_types: Option<Vec<String>>

Events with these types should be excluded.

senders: Option<Vec<String>>

Events from these senders should be included.

types: Option<Vec<String>>

Events with these types should be included.
