Enum InsertOp 

pub enum InsertOp {
    Append,
    Overwrite,
    Replace,
}

Variants

Append

Appends new rows to the existing table without modifying any existing rows. This corresponds to the SQL INSERT INTO query.

Overwrite

Overwrites all existing rows in the table with the new rows. This corresponds to the SQL INSERT OVERWRITE query.

Replace

If any existing rows collides with the inserted rows (typically based on a unique key or primary key), those existing rows are replaced. This corresponds to the SQL REPLACE INTO query and its equivalents.

Implementations

impl InsertOp

pub fn name(&self) -> &str

Return a descriptive name of this InsertOp

Trait Implementations

impl Clone for InsertOp

fn clone(&self) -> InsertOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for InsertOp

impl Debug for InsertOp

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

Formats the value using the given formatter.

impl Display for InsertOp

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

Formats the value using the given formatter.

impl Eq for InsertOp

impl Hash for InsertOp

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InsertOp

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for InsertOp

fn partial_cmp(&self, other: &InsertOp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
