Struct edgedb_tokio::state::ConfigModifier

pub struct ConfigModifier<'a> { /* private fields */ }

Utility object used to modify config

This object is passed to Fn closure and ConfigDelta::apply.

Implementations

impl ConfigModifier<'_>

pub fn set<T: QueryArg>(&mut self, key: &str, value: T)

Set configuration setting to a value

Panics

This methods panics if value cannot be converted into dynamically typed Value (QueryArg::to_value() method returns error). To avoid this panic use either native EdgeDB types (e.g. edgedb_protocol::model::Datetime instead of std::time::SystemTime or call to_value manually before passing to set.

pub fn unset(&mut self, key: &str)

Unset the global variable

In most cases this will effectively set the variable to a default value.

To set setting to the actual empty value use set("name", Value::Nothing).
