Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unset(DataType)

An unset value retaining its declared type.

Bool(bool)

A boolean value.

Char(char)

A character value.

Int8(i8)

A signed integer value.

Int16(i16)

A signed integer value.

Int32(i32)

A signed integer value.

Int64(i64)

A signed integer value.

Int128(i128)

A signed integer value.

UInt8(u8)

An unsigned integer value.

UInt16(u16)

An unsigned integer value.

UInt32(u32)

An unsigned integer value.

UInt64(u64)

An unsigned integer value.

UInt128(u128)

An unsigned integer value.

Float32(f32)

A 32-bit floating-point value.

Float64(f64)

A 64-bit floating-point value.

BigInteger(&'a BigInt)

An arbitrary-precision integer.

BigDecimal(&'a BigDecimal)

An arbitrary-precision decimal.

String(&'a str)

A string value.

Date(&'a NaiveDate)

A calendar date.

Time(&'a NaiveTime)

A time-of-day value.
