Enum ReadStatus

pub enum ReadStatus {
    Done,
    NotDone,
}

A read status.

Variants

Implementations

impl ReadStatus

pub fn check<R>(reader: &mut R) -> Result<ReadStatus, Error>

where R: BufRead,

Returns the read status of a reader.

Returns

Returns ReadStatus::Done if no more data remains to be read in the reader, otherwise returns ReadStatus::NotDone if any data remains. The reader may attempt to fill the underlying buffer to check for more data. An error in this processed is returned.

pub fn is_done(&self) -> bool

Returns true if read status is ReadStatus::Done.

pub fn is_not_done(&self) -> bool

Returns true if read status is ReadStatus::NotDone.

Trait Implementations

impl Clone for ReadStatus

fn clone(&self) -> ReadStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadStatus

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

Formats the value using the given formatter.

impl PartialEq for ReadStatus

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