Implementations

impl StateErr

pub fn from(value: LV2_State_Status) -> Result<(), StateErr>

Convert a raw status flag to a result or possible error value.

pub fn into(result: Result<(), StateErr>) -> LV2_State_Status

Convert a result to a raw status flag.

Trait Implementations

impl Clone for StateErr

fn clone(&self) -> StateErr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateErr

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

Formats the value using the given formatter.

impl PartialEq for StateErr

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