The properties (metadata) of a column.

Fields (Non-exhaustive)

This struct is marked as 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.
is_case_sensitive: bool

A value that indicates whether the column is case-sensitive.

is_currency: bool

A value that indicates whether the column contains currency values.

is_signed: bool

A value that indicates whether an integer column is signed.

label: Option<String>

The label for the column.

name: Option<String>

The name of the column.

nullable: i32

A value that indicates whether the column is nullable.

precision: i32

The precision value of a decimal number column.

scale: i32

The scale value of a decimal number column.

schema_name: Option<String>

The name of the schema that contains the table that includes the column.

table_name: Option<String>

The name of the table that includes the column.

type_name: Option<String>

The database-specific data type of the column.

length: i32

The length of the column.

column_default: Option<String>

The default value of the column.
