Struct DirectSchemaChangePolicy

#[non_exhaustive]
pub struct DirectSchemaChangePolicy {
    pub enable_update_catalog: Option<bool>,
    pub update_behavior: Option<UpdateCatalogBehavior>,
    pub table: Option<String>,
    pub database: Option<String>,
}

A policy that specifies update behavior for the crawler.

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.

enable_update_catalog: Option<bool>

Whether to use the specified update behavior when the crawler finds a changed schema.

update_behavior: Option<UpdateCatalogBehavior>

The update behavior when the crawler finds a changed schema.

table: Option<String>

Specifies the table in the database that the schema change policy applies to.

database: Option<String>

Specifies the database that the schema change policy applies to.

Implementations

impl DirectSchemaChangePolicy

pub fn enable_update_catalog(&self) -> Option<bool>

Whether to use the specified update behavior when the crawler finds a changed schema.

pub fn update_behavior(&self) -> Option<&UpdateCatalogBehavior>

The update behavior when the crawler finds a changed schema.

pub fn table(&self) -> Option<&str>

Specifies the table in the database that the schema change policy applies to.

pub fn database(&self) -> Option<&str>

Specifies the database that the schema change policy applies to.

impl DirectSchemaChangePolicy

pub fn builder() -> DirectSchemaChangePolicyBuilder

Creates a new builder-style object to manufacture DirectSchemaChangePolicy.

Trait Implementations

impl Clone for DirectSchemaChangePolicy

fn clone(&self) -> DirectSchemaChangePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DirectSchemaChangePolicy

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

Formats the value using the given formatter.

impl PartialEq for DirectSchemaChangePolicy

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

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

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

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