Struct Session 

pub struct Session { /* private fields */ }

The settings a session has, by name.

Every setting the engine has, not only the ones somebody changed. A reader of this is answering “what is it now”, so a name that is missing means the engine does not have that setting rather than that it is at its default.

Implementations

impl Session

pub fn new() -> Self

A session that knows nothing, which is what a caller with no database behind it has.

pub fn set(&mut self, name: &str, value: impl Into<String>)

Records what one setting is now.

pub fn get(&self, name: &str) -> Option<&str>

What that setting is now, and None for a name this session has no answer for.

pub fn iter(&self) -> impl Iterator<Item = (&str, &str)>

Every setting and its value, in name order.

pub fn is_empty(&self) -> bool

Whether nothing has been recorded.
