Trait CreateIndex

pub trait CreateIndex<'until_build> {
    // Required methods
    fn unique(self) -> Self;
    fn if_not_exists(self) -> Self;
    fn add_column(self, column: &'until_build str) -> Self;
    fn set_condition(self, condition: String) -> Self;
    fn build(self) -> Result<String, Error>;
}

Representation of a CREATE INDEX builder.

Required Methods

fn unique(self) -> Self

Creates a unique index.

Null values are considered different from all other null values.

fn if_not_exists(self) -> Self

Creates the index only if it doesn’t exist yet.

fn add_column(self, column: &'until_build str) -> Self

Adds a column to the index.

Parameter:

• column: String representing the column to index.

fn set_condition(self, condition: String) -> Self

Sets the condition to apply. This will build a partial index.

Parameter:

• condition: String representing condition to apply the index to

fn build(self) -> Result<String, Error>

This method is used to build the create index operation

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
