Trait Implementations

impl Clone for ColType

fn clone(&self) -> ColType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColType

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

Formats the value using the given formatter.

impl Display for ColType

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

Formats the value using the given formatter.

impl FromBytes for ColType

fn from_bytes(bytes: &[u8]) -> Result<ColType>

It gets and array of bytes and should return an implementor struct.

impl FromCursor for ColType

fn from_cursor(cursor: &mut Cursor<&[u8]>) -> Result<ColType>

It should return an implementor from an io::Cursor over an array of bytes.

impl Hash for ColType

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for ColType

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<ColType> for ColType

fn eq(&self, other: &ColType) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<ColType> for ColType

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for ColType

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

Serializes given value using the cursor.

fn serialize_to_vec(&self) -> Vec<u8>

Wrapper for easily starting hierarchical serialization.

impl TryFrom<i16> for ColType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i16) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ColType
