Enum EncryptedParamType 

#[non_exhaustive]
pub enum EncryptedParamType {
    Decimal {
        precision: u8,
        scale: u8,
    },
    Time {
        scale: u8,
    },
    DateTime2 {
        scale: u8,
    },
    DateTimeOffset {
        scale: u8,
    },
    DateTime,
    Char {
        length: u16,
    },
    NChar {
        length: u16,
    },
    Binary {
        length: u16,
    },
}

The explicit SQL type for an Always Encrypted parameter whose value cannot convey it (see numeric, time, datetime2, datetimeoffset, datetime). Carries the precision/scale/length the encrypted column requires the declared parameter type to match exactly.

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.

Decimal

decimal(precision, scale).

Fields

precision: u8

Total number of significant digits (1–38).

scale: u8

Number of digits to the right of the decimal point.

Time

time(scale).

Fields

scale: u8

Fractional-second digits (0–7).

DateTime2

datetime2(scale).

Fields

scale: u8

Fractional-second digits (0–7).

DateTimeOffset

datetimeoffset(scale).

Fields

scale: u8

Fractional-second digits (0–7).

DateTime

Legacy datetime (8 bytes; ~3.33 ms resolution).

Char

Fixed-length char(length) (length in bytes; the encrypted column must use a *_BIN2 collation, and the value is encoded in its code page).

Fields

length: u16

Declared length in bytes.

NChar

Fixed-length nchar(length) (length in UTF-16 characters; the encrypted column must use a *_BIN2 collation).

Fields

length: u16

Declared length in characters.

Binary

Fixed-length binary(length) (length in bytes).

Fields

length: u16

Declared length in bytes.

Trait Implementations

impl Clone for EncryptedParamType

fn clone(&self) -> EncryptedParamType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EncryptedParamType

impl Debug for EncryptedParamType

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

Formats the value using the given formatter.

impl Eq for EncryptedParamType

impl PartialEq for EncryptedParamType

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