Variants

Text

An unrestricted text string.

Examples

assert!(msi::ColumnCategory::Text.validate("Hello, World!"));

UpperCase

A text string containing no lowercase letters.

Examples

assert!(msi::ColumnCategory::UpperCase.validate("HELLO, WORLD!"));
assert!(!msi::ColumnCategory::UpperCase.validate("Hello, World!"));

LowerCase

A text string containing no uppercase letters.

Examples

assert!(msi::ColumnCategory::LowerCase.validate("hello, world!"));
assert!(!msi::ColumnCategory::LowerCase.validate("Hello, World!"));

Integer

A signed 16-bit integer.

Examples

assert!(msi::ColumnCategory::Integer.validate("32767"));
assert!(msi::ColumnCategory::Integer.validate("-47"));
assert!(!msi::ColumnCategory::Integer.validate("40000"));

DoubleInteger

A signed 32-bit integer.

Examples

assert!(msi::ColumnCategory::DoubleInteger.validate("2147483647"));
assert!(msi::ColumnCategory::DoubleInteger.validate("-99999"));
assert!(!msi::ColumnCategory::DoubleInteger.validate("3000000000"));

Identifier

A string identifier (such as a table or column name). May only contain alphanumerics, underscores, and periods, and must start with a letter or underscore.

Examples

assert!(msi::ColumnCategory::Identifier.validate("HelloWorld"));
assert!(msi::ColumnCategory::Identifier.validate("_99.Bottles"));
assert!(!msi::ColumnCategory::Identifier.validate("3.14159"));

Property

A string that is either an identifier (see above), or a reference to an environment variable (which consists of a % character followed by an identifier).

Examples

assert!(msi::ColumnCategory::Property.validate("HelloWorld"));
assert!(msi::ColumnCategory::Property.validate("%HelloWorld"));
assert!(!msi::ColumnCategory::Property.validate("Hello%World"));

Filename

The name of a file or directory.

WildCardFilename

A filename that can contain shell glob wildcards.

Path

A string containing an absolute filepath.

Paths

A string containing a semicolon-separated list of absolute filepaths.

AnyPath
