Struct TransactionCharacteristics

pub struct TransactionCharacteristics<'a>(/* private fields */);

This tracker type indicates that transaction characteristics are available.

The characteristics tracker data string may be empty, or it may contain one or more SQL statements, each terminated by a semicolon.

Implementations

impl<'a> TransactionCharacteristics<'a>

pub fn new(value: impl Into<Cow<'a, [u8]>>) -> TransactionCharacteristics<'a>

pub fn as_bytes(&self) -> &[u8]

Returns a raw value.

pub fn as_str(&self) -> Cow<'_, str>

Returns a value (lossy converted).

pub fn into_owned(self) -> TransactionCharacteristics<'static>

Returns a 'static version of self.

Trait Implementations

impl<'a> Clone for TransactionCharacteristics<'a>

fn clone(&self) -> TransactionCharacteristics<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TransactionCharacteristics<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for TransactionCharacteristics<'a>

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'de> MyDeserialize<'de> for TransactionCharacteristics<'de>

const SIZE: Option<usize> = None

Size hint of a serialized value (in bytes), if it’s constant.

type Ctx = ()

Some structs defines deserialization in the context of another value.

fn deserialize( _: <TransactionCharacteristics<'de> as MyDeserialize<'de>>::Ctx, buf: &mut ParseBuf<'de>, ) -> Result<TransactionCharacteristics<'de>, Error>

Deserializes self from the given buf.

impl MySerialize for TransactionCharacteristics<'_>

fn serialize(&self, buf: &mut Vec<u8>)

Serializes self into the buf.

impl<'a> PartialEq for TransactionCharacteristics<'a>

fn eq(&self, other: &TransactionCharacteristics<'a>) -> 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.
