Struct SourceEnvironment 

#[non_exhaustive]
pub struct SourceEnvironment {
    pub default_database: String,
    pub schema_search_path: Vec<String>,
    pub metadata_store_dataset: String,
    /* private fields */
}

Represents the default source environment values for the translation.

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.

default_database: String

The default database name to fully qualify SQL objects when their database name is missing.

schema_search_path: Vec<String>

The schema search path. When SQL objects are missing schema name, translation engine will search through this list to find the value.

metadata_store_dataset: String

Optional. Expects a validQ BigQuery dataset ID that exists, e.g., project-123.metadata_store_123. If specified, translation will search and read the required schema information from a metadata store in this dataset. If metadata store doesn’t exist, translation will parse the metadata file and upload the schema info to a temp table in the dataset to speed up future translation jobs.

Implementations

impl SourceEnvironment

pub fn new() -> Self

pub fn set_default_database<T: Into<String>>(self, v: T) -> Self

Sets the value of default_database.

Example

let x = SourceEnvironment::new().set_default_database("example");

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

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of schema_search_path.

Example

let x = SourceEnvironment::new().set_schema_search_path(["a", "b", "c"]);

pub fn set_metadata_store_dataset<T: Into<String>>(self, v: T) -> Self

Sets the value of metadata_store_dataset.

Example

let x = SourceEnvironment::new().set_metadata_store_dataset("example");

Trait Implementations

impl Clone for SourceEnvironment

fn clone(&self) -> SourceEnvironment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceEnvironment

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

Formats the value using the given formatter.

impl Default for SourceEnvironment

fn default() -> SourceEnvironment

Returns the “default value” for a type.

impl Message for SourceEnvironment

fn typename() -> &'static str

The typename of this message.

impl PartialEq for SourceEnvironment

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