Enum lsmlite_rs::LsmCursorSeekOp

#[repr(C)]
pub enum LsmCursorSeekOp {
    LsmCursorSeekLe = -1,
    LsmCursorSeekEq = 0,
    LsmCursorSeekGe = 1,
}

These are the different seek operations of a cursor.

Variants

LsmCursorSeekLe = -1

When seeking with a LsmCursor using this mode, the cursor is positioned on the record indexed by the given key if found, or the record right before it in the total order of keys (as per memcmp). If the database contains no such record, the cursor is left at EOF.

LsmCursorSeekEq = 0

When seeking with a LsmCursor using the mode, the cursor is positioned on the record indexed by the given key if found, or at EOF if such record does not exist in the database.

LsmCursorSeekGe = 1

When seeking with a LsmCursor using this mode, the cursor is positioned on the record indexed by the given key if found, or the record right after it in the total order of keys (as per memcmp). If the database contains no such record, the cursor is left at EOF.

Trait Implementations

impl Clone for LsmCursorSeekOp

fn clone(&self) -> LsmCursorSeekOp

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LsmCursorSeekOp

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for LsmCursorSeekOp

fn eq(&self, other: &LsmCursorSeekOp) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<i32> for LsmCursorSeekOp

type Error = LsmErrorCode

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
