Struct nusb::transfer::Completion

pub struct Completion<T> {
    pub data: T,
    pub status: Result<(), TransferError>,
}

Status and data returned on transfer completion.

A transfer can return partial data even in the case of failure or cancellation, thus this is a struct containing both data and status rather than a Result. Use into_result to ignore a partial transfer and get a Result.

Fields

data: T

Returned data or buffer to re-use.

status: Result<(), TransferError>

Indicates successful completion or error.

Implementations

impl<T> Completion<T>

pub fn into_result(self) -> Result<T, TransferError>

Ignore any partial completion, turning self into a Result containing either the completed buffer for a successful transfer or a TransferError.

Trait Implementations

impl<T: Clone> Clone for Completion<T>

fn clone(&self) -> Completion<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Completion<T>

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

Formats the value using the given formatter.

impl TryFrom<Completion<ResponseBuffer>> for ResponseBuffer

type Error = TransferError

The type returned in the event of a conversion error.

fn try_from(c: Completion<ResponseBuffer>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Completion<Vec<u8>>> for Vec<u8>

type Error = TransferError

The type returned in the event of a conversion error.

fn try_from(c: Completion<Vec<u8>>) -> Result<Self, Self::Error>
