Struct JoinConfig 

pub struct JoinConfig {
    pub no_sort: bool,
}

Configuration properties for a JoinCursor.

Pass to Database::join to control join cursor behaviour.

Default

• no_sort = false — cursors are automatically sorted by estimated duplicate count (smallest set first) so that the join algorithm can prune candidates as early as possible. Set no_sort = true if you have already ordered the cursor array optimally.

Fields

no_sort: bool

Disables automatic cursor sorting when true.

Implementations

impl JoinConfig

pub fn new() -> Self

Creates a new JoinConfig with all defaults.

pub fn set_no_sort(&mut self, no_sort: bool)

Sets whether automatic cursor sorting is disabled.

pub fn with_no_sort(self, no_sort: bool) -> Self

Builder-style no_sort setter.

pub fn get_no_sort(&self) -> bool

Returns true if automatic cursor sorting is disabled.
