Trait Implementations

impl Clone for IvfData

fn clone(&self) -> IvfData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IvfData

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

Formats the value using the given formatter.

impl PartialEq for IvfData

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

impl TryFrom<&IvfData> for Ivf

type Error = Error

The type returned in the event of a conversion error.

fn try_from(meta: &IvfData) -> Result<Self>

Performs the conversion.

impl TryFrom<Ivf> for IvfData

type Error = Error

The type returned in the event of a conversion error.

fn try_from(proto: PbIvf) -> Result<Self>

Performs the conversion.
