Implementations

impl ChangeType

pub fn short_string(&self) -> &'static str

Returns a short string representation of this ChangeType

pub fn to_byte_value(&self) -> u8

Returns the byte value representation used for serialization

pub fn from_byte_value(value: u8) -> Result<Self, String>

Creates a ChangeType from its byte value representation

Errors

Returns an error if the byte value doesn’t correspond to any ChangeType

Trait Implementations

impl Clone for ChangeType

fn clone(&self) -> ChangeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeType

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

Formats the value using the given formatter.

impl Display for ChangeType

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

Formats the value using the given formatter.

impl Hash for ChangeType

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 PartialEq for ChangeType

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