Enum aws_sdk_redshiftdata::model::Field

#[non_exhaustive]
pub enum Field {
    BlobValue(Blob),
    BooleanValue(bool),
    DoubleValue(f64),
    IsNull(bool),
    LongValue(i64),
    StringValue(String),
    Unknown,
}

A data value in a column.

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.

BlobValue(Blob)

A value of the BLOB data type.

Tuple Fields of BlobValue

0: Blob

BooleanValue(bool)

A value of the Boolean data type.

Tuple Fields of BooleanValue

0: bool

DoubleValue(f64)

A value of the double data type.

Tuple Fields of DoubleValue

0: f64

IsNull(bool)

A value that indicates whether the data is NULL.

Tuple Fields of IsNull

0: bool

LongValue(i64)

A value of the long data type.

Tuple Fields of LongValue

0: i64

StringValue(String)

A value of the string data type.

Tuple Fields of StringValue

0: String

Unknown

The Unknown variant represents cases where new union variant was received. Consider upgrading the SDK to the latest available version. An unknown enum variant

Note: If you encounter this error, consider upgrading your SDK to the latest version. The Unknown variant represents cases where the server sent a value that wasn’t recognized by the client. This can happen when the server adds new functionality, but the client has not been updated. To investigate this, consider turning on debug logging to print the raw HTTP response.

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

Implementations

impl Field

pub fn as_blob_value(&self) -> Result<&Blob, &Self>

Tries to convert the enum instance into BlobValue, extracting the inner Blob. Returns Err(&Self) if it can’t be converted.

pub fn is_blob_value(&self) -> bool

Returns true if this is a BlobValue.

pub fn as_boolean_value(&self) -> Result<&bool, &Self>

Tries to convert the enum instance into BooleanValue, extracting the inner bool. Returns Err(&Self) if it can’t be converted.

pub fn is_boolean_value(&self) -> bool

Returns true if this is a BooleanValue.

pub fn as_double_value(&self) -> Result<&f64, &Self>

Tries to convert the enum instance into DoubleValue, extracting the inner f64. Returns Err(&Self) if it can’t be converted.

pub fn is_double_value(&self) -> bool

Returns true if this is a DoubleValue.

pub fn as_is_null(&self) -> Result<&bool, &Self>

Tries to convert the enum instance into IsNull, extracting the inner bool. Returns Err(&Self) if it can’t be converted.

pub fn is_is_null(&self) -> bool

Returns true if this is a IsNull.

pub fn as_long_value(&self) -> Result<&i64, &Self>

Tries to convert the enum instance into LongValue, extracting the inner i64. Returns Err(&Self) if it can’t be converted.

pub fn is_long_value(&self) -> bool

Returns true if this is a LongValue.

pub fn as_string_value(&self) -> Result<&String, &Self>

Tries to convert the enum instance into StringValue, extracting the inner String. Returns Err(&Self) if it can’t be converted.

pub fn is_string_value(&self) -> bool

Returns true if this is a StringValue.

pub fn is_unknown(&self) -> bool

Returns true if the enum instance is the Unknown variant.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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