Enum SeekOp 

pub enum SeekOp {
    GE {
        eq_only: bool,
    },
    GT,
    LE {
        eq_only: bool,
    },
    LT,
}

The match condition of a table/index seek.

Variants

GE

If eq_only is true, this means in practice: We are iterating forwards, but we are really looking for an exact match on the seek key.

Fields

eq_only: bool

GT

LE

If eq_only is true, this means in practice: We are iterating backwards, but we are really looking for an exact match on the seek key.

Fields

eq_only: bool

LT

Implementations

impl SeekOp

pub fn iteration_direction(&self) -> IterationDirection

A given seek op implies an iteration direction.

For example, a seek with SeekOp::GT implies: Find the first table/index key that compares greater than the seek key -> used in forwards iteration.

A seek with SeekOp::LE implies: Find the last table/index key that compares less than or equal to the seek key -> used in backwards iteration.

pub fn eq_only(&self) -> bool

pub fn reverse(&self) -> Self
