Implementations

impl ColumnInfoBuilder

pub fn catalog_name(self, input: impl Into<String>) -> Self

The catalog to which the query results belong.

pub fn set_catalog_name(self, input: Option<String>) -> Self

The catalog to which the query results belong.

pub fn get_catalog_name(&self) -> &Option<String>

The catalog to which the query results belong.

pub fn schema_name(self, input: impl Into<String>) -> Self

The schema name (database name) to which the query results belong.

pub fn set_schema_name(self, input: Option<String>) -> Self

The schema name (database name) to which the query results belong.

pub fn get_schema_name(&self) -> &Option<String>

The schema name (database name) to which the query results belong.

pub fn table_name(self, input: impl Into<String>) -> Self

The table name for the query results.

pub fn set_table_name(self, input: Option<String>) -> Self

The table name for the query results.

pub fn get_table_name(&self) -> &Option<String>

The table name for the query results.

pub fn name(self, input: impl Into<String>) -> Self

The name of the column.

This field is required.

pub fn set_name(self, input: Option<String>) -> Self

The name of the column.

pub fn get_name(&self) -> &Option<String>

The name of the column.

pub fn label(self, input: impl Into<String>) -> Self

A column label.

pub fn set_label(self, input: Option<String>) -> Self

A column label.

pub fn get_label(&self) -> &Option<String>

A column label.

pub fn type(self, input: impl Into<String>) -> Self

The data type of the column.

This field is required.

pub fn set_type(self, input: Option<String>) -> Self

The data type of the column.

pub fn get_type(&self) -> &Option<String>

The data type of the column.

pub fn precision(self, input: i32) -> Self

For DECIMAL data types, specifies the total number of digits, up to 38. For performance reasons, we recommend up to 18 digits.

pub fn set_precision(self, input: Option<i32>) -> Self

For DECIMAL data types, specifies the total number of digits, up to 38. For performance reasons, we recommend up to 18 digits.

pub fn get_precision(&self) -> &Option<i32>

For DECIMAL data types, specifies the total number of digits, up to 38. For performance reasons, we recommend up to 18 digits.

pub fn scale(self, input: i32) -> Self

For DECIMAL data types, specifies the total number of digits in the fractional part of the value. Defaults to 0.

pub fn set_scale(self, input: Option<i32>) -> Self

For DECIMAL data types, specifies the total number of digits in the fractional part of the value. Defaults to 0.

pub fn get_scale(&self) -> &Option<i32>

For DECIMAL data types, specifies the total number of digits in the fractional part of the value. Defaults to 0.

pub fn nullable(self, input: ColumnNullable) -> Self

Unsupported constraint. This value always shows as UNKNOWN.

pub fn set_nullable(self, input: Option<ColumnNullable>) -> Self

Unsupported constraint. This value always shows as UNKNOWN.

pub fn get_nullable(&self) -> &Option<ColumnNullable>

Unsupported constraint. This value always shows as UNKNOWN.

pub fn case_sensitive(self, input: bool) -> Self

Indicates whether values in the column are case-sensitive.

pub fn set_case_sensitive(self, input: Option<bool>) -> Self

Indicates whether values in the column are case-sensitive.

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

Indicates whether values in the column are case-sensitive.

pub fn build(self) -> Result<ColumnInfo, BuildError>

Consumes the builder and constructs a ColumnInfo. This method will fail if any of the following fields are not set:

• name
• r#type

Trait Implementations

impl Clone for ColumnInfoBuilder

fn clone(&self) -> ColumnInfoBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnInfoBuilder

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

Formats the value using the given formatter.

impl Default for ColumnInfoBuilder

fn default() -> ColumnInfoBuilder

Returns the “default value” for a type.

impl PartialEq for ColumnInfoBuilder

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