Enum MutationStrategy 

#[non_exhaustive]
pub enum MutationStrategy {
    FunctionCall,
    DirectSql,
}

Strategy used by an adapter for executing mutations.

Adapters that use stored database functions (PostgreSQL, MySQL, SQL Server) use FunctionCall. Adapters that generate INSERT/UPDATE/DELETE SQL directly (SQLite) use DirectSql.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

FunctionCall

Mutations execute via stored database functions (SELECT * FROM fn_create_user($1, $2)).

DirectSql

Mutations execute via direct SQL (INSERT INTO ... RETURNING *).

Trait Implementations

impl Clone for MutationStrategy

fn clone(&self) -> MutationStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MutationStrategy

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

Formats the value using the given formatter.

impl PartialEq for MutationStrategy

fn eq(&self, other: &MutationStrategy) -> 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.
