Implementations

impl FilterType

pub fn from_u8(n: u8) -> Option<FilterType>

u8 -> Self. Temporary solution until Rust provides a canonical one.

Trait Implementations

impl Clone for FilterType

fn clone(&self) -> FilterType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FilterType

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

Formats the value using the given formatter.

impl<W: Write> Parameter<Encoder<W>> for FilterType

fn set_param(self, this: &mut Encoder<W>)

impl PartialEq<FilterType> for FilterType

fn eq(&self, other: &FilterType) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
