Struct NullableString 

pub struct NullableString(pub Option<String>);

Represents a sequence of characters or null.

For non-null strings, first the length N is given as an INT16. Then N bytes follow which are the UTF-8 encoding of the character sequence. A null value is encoded with length of -1 and there are no following bytes.

0: Option<String>

Trait Implementations

impl Clone for NullableString

fn clone(&self) -> NullableString

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NullableString

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

Formats the value using the given formatter.

impl Default for NullableString

fn default() -> NullableString

Returns the “default value” for a type.

impl Hash for NullableString

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

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 Ord for NullableString

fn cmp(&self, other: &NullableString) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NullableString

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

impl PartialOrd for NullableString

fn partial_cmp(&self, other: &NullableString) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<R> ReadType<R> for NullableString

where R: Read,

fn read(reader: &mut R) -> Result<Self, ReadError>

impl<W> WriteType<W> for NullableString

where W: Write,

fn write(&self, writer: &mut W) -> Result<(), WriteError>
