Struct GeneratedExpressionInfo 

#[non_exhaustive]
pub struct GeneratedExpressionInfo {
    pub generation_expression: Option<String>,
    pub asynchronous: Option<bool>,
    pub stored: Option<bool>,
    /* private fields */
}

Definition of the expression used to generate the field.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

generation_expression: Option<String>

Optional. The generation expression (e.g. AI.EMBED(…)) used to generate the field.

asynchronous: Option<bool>

Optional. Whether the column generation is done asynchronously.

stored: Option<bool>

Optional. Whether the generated column is stored in the table.

Implementations

impl GeneratedExpressionInfo

pub fn new() -> Self

Creates a new default instance.

pub fn set_generation_expression<T>(self, v: T) -> Self

where T: Into<String>,

Sets the value of generation_expression.

Example

let x = GeneratedExpressionInfo::new().set_generation_expression("example");

pub fn set_or_clear_generation_expression<T>(self, v: Option<T>) -> Self

where T: Into<String>,

Sets or clears the value of generation_expression.

Example

let x = GeneratedExpressionInfo::new().set_or_clear_generation_expression(Some("example"));
let x = GeneratedExpressionInfo::new().set_or_clear_generation_expression(None::<String>);

pub fn set_asynchronous<T>(self, v: T) -> Self

where T: Into<bool>,

Sets the value of asynchronous.

Example

let x = GeneratedExpressionInfo::new().set_asynchronous(true);

pub fn set_or_clear_asynchronous<T>(self, v: Option<T>) -> Self

where T: Into<bool>,

Sets or clears the value of asynchronous.

Example

let x = GeneratedExpressionInfo::new().set_or_clear_asynchronous(Some(false));
let x = GeneratedExpressionInfo::new().set_or_clear_asynchronous(None::<bool>);

pub fn set_stored<T>(self, v: T) -> Self

where T: Into<bool>,

Sets the value of stored.

Example

let x = GeneratedExpressionInfo::new().set_stored(true);

pub fn set_or_clear_stored<T>(self, v: Option<T>) -> Self

where T: Into<bool>,

Sets or clears the value of stored.

Example

let x = GeneratedExpressionInfo::new().set_or_clear_stored(Some(false));
let x = GeneratedExpressionInfo::new().set_or_clear_stored(None::<bool>);
